Kristof's Elven Catapult

Recommended Posts

So @Zink's thread here...

 

...inspired me to try my hand at creating an Elven catapult with Fusion 360 and my printer.  Rather than hijack his thread anymore, it's time to create its own thread.

 

I'm not anywhere near done, but I went ahead and printed out a prototype of my design so I could get a better feel for things and tweak it. Here is Sir ForScale checking over the construction so far:

I'm glad I decided to print out a prototype now.  I found that my tolerances are too tight for some of the assembly, and that I need to fix how the center piece goes in.

 

I could probably merge it all into one piece, and print it as a single piece, or maybe two, but I am trying to keep the pieces fairly flat so that it can be mailed in an envelope.

 

Trying to figure out what elven looking wheels without spokes would look like, as I think spoked wheels might be too delicate to print at this size

Like how it looks so far. ::): Maybe a bit small but resizing isn't that hard is it? I like the idea of having spoked wheels but understand you've got limits. Would it be possible to make a solid wheel with a bit of detailing to look something like these?

Hmm...

The decorations are too fine on those wheels to do, but a similar 3 spoke design might be doable. 

and now I want to to a chariot...

Welcome to my world. See one thing which leads to wanting another and on and on. 

 

Even thick spokes based on something like this would look cool.

Wheel rim around the outside, fill in the middle of the leaves and add a hub. 

 

You've probably mentioned before but what printer are you using? I'm really interested in getting one sometime but haven't pulled the trigger yet yet.

I have a Prusa i3 Mk2S.  I'm told it's capable of being tuned to finer details than I'm getting, but I haven't made the effort to tune it further, as I'm relatively happy with what I'm getting.

I completely redrew this to upsize it, and fix some fit and construction problems  New prototype is on the printer now.

2nd prototype print finished. The first prototype is in the background.

Sir ForScale is telling me I'm almost finished with it, and to just get it done.

 

I'm inclined to agree with him.  I only have a couple of pieces left to make it "workable" (in the sense that it will assemble, and be a reasonable facsimile of a catapult).

 

BUT...I'm growing increasingly unhappy with it. Why?

 

Because the perfectionist part of me wants to  spend the time to really polish it up and refine it as best I can, while the practical part of me just wants to finish it and get back to my Cowboy UV project.

I like it. There's always more little details a person could add but I think the only thing you really need is a roller at the back for pulling the arm down.

This is as done as it's going to be for awhile:

I enjoyed doing this just from the perspective of the learning experience and exploring mine and my printer's capabilities.

So @Zink got the catapult I sent him painted up - you can see it here:

http://forum.reapermini.com/index.php?/topic/82724-siege-accessories/&do=findComment&comment=1760353

I've also uploaded it to Thingiverse, using his photo - you can search for it by elven catapult or my forum name here. 

I only uploaded it this morning, and it's gotten 100 downloads already, which means it's fast on track to becoming my most popular design there - my most popular designs there have only garnered between 400-500 downloads each, and they were posted in Oct of last year. 

I may have to do more of these types of things.

You did all the work but it still feels good to have a small part in this. Glad it's turning out popular. It really is a nice little catapult and it's sized perfectly for what I wanted.

Once I get mine running & I know what I'm doing I'll have to try it out. Thanks for posting!!

I never would have created it if you hadn't inspired me.  Given its apparent popularity, I may have to consider doing more pieces based on things I see people asking for here.  It might be time to browse through some of the "________ we'd like to see" threads.

      Good day everyone, I've been working on a diorama display for some time now and I thought some of you may like the see my progress. I used AutoCad for my sketches and Inventor to build the 3D model. Then I used Blender to texture the model and Slicer to generate de code for my Prusa printer. The following pictures are the steps I went through so far. It’s my first big project. It's taking long but it's a learning experience. Let me know what you think about it so far.
       
      The first image is a screenshot of the final model in Inventor.

       
      Some sketches in AutoCad software.

       
      Floor part in Invetor software.

       
      Generating the code of the floor in Prusa Slicer software.

       
      I got a printing error while printing the floor. The plastic filament and I had to stop the print.

       
      On the next picture, we can see how the parts are on the inside. There is some supports but most of the part is empty to save on printing time and material.

       
      I decided to print the remining floor tiles individually to salvage what I had already been printing. I then glued each tile on the base.

       
      I had another printing error on the column, and I had the print another one.

       
      The column was printed at the highest level of quality my Prusa i3 MK3S can print, which is at a 0.05mm of precision.

       
      The arch was also printed at 0.05mm.
       
      The level of detail is amazing. Even the ring was printed flawlessly without support.

       
      Here’s a screenshot of the wall assembly after I completed texturing it in Blender.

       
      Here’s a screenshot of the wall assembly in Slicer. I generated the code with supports to make sure the door arch would be print perfectly.

       
      It looks perfect like this, so I didn’t see a problem coming.

       
      Some parts of mu model were not right, there were some gaps. The software filled these gaps with support material, so when I see the issue, I decided not to stop the printing session. The support material is showing in drak green the the simulation.

       
      After, when I generated the code without support, I could clearly see the gaps. I think this happened because there were errors, holes I didn’t correct or masking I didn’t remove, on the model I imported from Blender. I will need to investigate farther.

       
      See the result after I removed all the support. Removing the support takes forever by the way. I’ll try to avoid supports if possible, in the future.

       
      Here’s a picture of the wall. It took 40 hours to print only and probably another 40 hours to build, texture and clean the model. I still need to fill the gaps the Greenstuff.

       
      Here are all the parts I printed for this project.

       
      And, all the parts together. I haven’t glue anything yet. There is still some sanding and cleaning to do. I will paint each part separately.

       
      I patched the gaps with liquid Green Stuff.

       
      Closeup of the first layer of liquid Green Stuff.

       
      I converted a 02712 Eye Best from Reaper Miniatures. This is the pewter version of model that was sculpted by Julie Guthrie. I added eye stalks from the 03440 Creature Components II, also from Reaper.

       

       

       
      The Eye Best will be pinned on the wall and the door. All the adventurers I'll be displaying on the diorama are from Reaper Miniatures Dungeon Dwellers brand. From left to right; 07012 Caerindra Thistlemoor, 07004 Stitch Thimbletoe, 07002 Baran Blacktree and 07008 Luwin Phost.

       

       
      The models can be moved from a recess to another to allow different layouts.

       

       
      More to come soon!

      Clorehaven & the Goblin Grotto, via @Kickstarter https://www.kickstarter.com/projects/printablescenery/clorehaven-and-the-goblin-grotto
       
       
      The picturesque town of Clorehaven  
      A lively tavern, a variety of interesting and useful stores and fine lodgings is all the weary adventurer could ask  for.
      The locals seem polite and friendly. The beautiful stone and wood buildings tell you this small town is prosperous and will someday grow into a much larger city. But under the surface of the town, Clorehaven keeps a dark and foreboding secret.  
      Beneath the neat hedgerows and well-kept homes there lies a sprawling complex of caverns. 
      The deep goblins are a sniveling race of green-skins, plying their trade in the strange flora and fauna they gather from around mysterious pools. 
      Design and build your own medieval buildings using the Clorehaven OpenLOCK system. From simple houses to huge complex structures, anything is possible. 
      Explore the Goblin Grotto using the modular Grotto cavern system. Walls and floors can be combined to create a huge variety of underground caverns or above ground structures. 
      Who knows what’s in store for those above and what lies in the depths below. Clorehaven and the Goblin Grotto - By Printable Scenery - the best 3D printable scenery in all the worlds. 
      All the models from Clorehaven & the Goblin Grotto are delivered as optimized STL files to print on home 3D printers.
      If you take the All-In Pledge, you also receive the free bonus items.   
      Clorehaven Pledge :   Clorehaven is constructed using the OpenLOCK tile system where quality detailed modular and functional buildings can be constructed in any shape and size whilst maintaining the true 1" grid system used for most role playing games. 
      This pledge contains the models to build the Townhouse, Cottage, Homestead, Grand Hostel, Cabin, Tavern, Chalet, Watchtower and Schist Stone Fences.  The Clorehaven Pledge includes the stretch goals labelled Clorehaven.
       As the Kickstarter progresses the free stretch goals will grow and expand Clorehaven from a town into a city.
      Goblin Grotto Pledge:  The free form caverns create natural and expansive cavern maps and tunnel systems quickly and dynamically. The cavern floors are designed to have a comparable 1" grid system for RPG whilst still maintaining the natural rock form.
       PLAY This pledge contains the Moon Effigy, the Goblin Cavern Floors, The Cavern Walls, The Cavern Tunnels, the Cavern Bridge, Rickety Bridges and the Gloom Creeper. The Goblin Grotto Pledgeincludes the stretch goals labelled Goblin Grotto.
       All of our 3D-printable models begin their life as hand drawn concepts. From there we digitally sculpt the models to create high detail STL files. The models are test printed and painted before released so that you know each model from Printable Scenery will print perfectly. 
       Printable Scenery created the OpenLOCK system in 2016. Since then it has become the standard. Its innovative seamless locking system revolutionized dungeon system. Printable Scenery open-sourced the design and it allows for free commercial use to third party designers such as Open Forge.

      I figured it was time to work on some Elves.  They're definitely the smallest part of my painted collection.

      The first batch is all from Reaper Miniatures.  

      These are the metal ones:


       

       

       
       

       
       

       
       

       

       
       
      The Drow who snuck in (from the box of Goodwill, no less)



      More from Reaper, but this time in Bones:


       
       

       

       
       

       
       

       
       

       

       

       
       

       

       
       

       
       


      And the others.  Mostly Stonehaven

      And since there are never enough terrain projects, I thought I'd give this one a mention.  Supposedly everything prints without supports too.
