  1. All right. I have gotten my power cylinders finished. After using an exacto knife to cut away the little extra bits I first did a layer of XTC 3D (an epoxy coating by smooth on) to give it a smooth finish. I then added the nuts and bolts, some nylon wire covering in the back, and then used matt black auto spray paint to finish it. Unfortunately between the XTC 3D and the paint I lost some of the sharp details and I screwed up and didn't center my nuts and bolts very well. Over all I'm happy with the end product seeing as I have about a $1.50 invested.

    After the XTC 3D layer:

    Bolts, nuts, and nylon wire covering:

    ...and the finished PCs:

    I guess I should get back to the T-21 parts soon.

  2. Well the two most common materials are PLA and ABS. The big problem with PLA is it is not very heat tolerant so there is the possibility of warping in a car or out in the sun. I'm not sure if any of the finishing epoxys give it add protection from the heat though they definitely strengthen it.

  3. Wow. TrainWreck, you are getting really good at creating 3-D printed models. Ever thought about doing the entire canteen version?

    I played around with the entire canteen last night. I wasn't really happy with my initial results so I just threw this out for now (it took me 10 minutes over three versions). I'll play with it some more when I get a chance.

    Thanks for the words!

  4. Since everyone seems to be having difficulty sourcing the faucet covers for the bee stingers I thought I would model one for everyone that can be printed if you have the means.

    I based the dimensions off the one I have so it is 6.25" x 4.5" x 4.5" with out the slight taper mine has. It also has a 1/10" thick wall.

    This is what it looks like:

    And here is the URL for the dropbox I put the .stl file in:

    Hope this helps someone!

    Cheers!

  5. Nicely done. I am excited to see the finished product.

    Aren't there 3D printing place online that will print your file and ship the product to you?

    Yes there are but it's as much a budget issue for me as anything. The local library is orders of magnatudes cheaper than the online services. Frankly I have so much going on right now it probably is for the best I have to wait on prints. Projects are starting to pile up in my shop.

    Thanks again for all the feedback!

  6. Dude, those power cylinders look awesome! Did you sand them at all before using the XTC?

    And again, I HIGHLY suggest printing the knobs separately.

    I also use 123D Design :)

    No sanding so far. The only issue I have with the stuff is it does soften the edges a bit. I haven't tried to sand the stuff so I don't know how hard it is.

    I'll have to go in and cut out the knobs. The two smaller ones won't be a problem but the large one will be a pain since it's sitting in that indent. Luckily it will be a while before that gets printed so I have time to play with it.

  7. Super! Makes me want to learn more about CAD drawing and 3D printing. Great job on both the radio and cylinders.

    Download a free copy of 123D Design. Autodesk (the company that makes it) has a bunch of tutorials on youtube (I think I just googled 123D Design tutorial). I was ready to rock and roll after about 20 minutes and the program is much easier to use then Blender or Fusion 360.
