Description

I am building PCBs once in a while. Since we all now got our MakerBots sitting beside us, it would be a pitty leaving all those little contraptions naked. Time has come for the parametric chassis!

This is a parametric box for all your precious electronics (and more). You can set up size, wall thickness, bolt size, bolt slanting, ... Just fire up your OpenSCAD and start playing around with it!

I would love to see those things in the wild!

Instructions

Check the OpenSCAD source. I tried my best to put all the important variables to the very top. I programmed the scad file so that the provided dimensions will always fit INSIDE the box. But the thicker you do the walls/bolts, the bigger the OUTER dimensions will get. Just fiddle around with it.

Wall thickness is set to 1mm which should result in walls without infills - giving you perfectly straight and smooth walls! (Infills in thin walls tend to destroy my objects quite often. Especially when going for tall objects).

One more thing: The file is set up to generate both bottom plane and top box at the same time. To change this, just look at the

module chassis

part and comment/uncomment the blocks you need.

If you have any questions, just drop me a line!

You need to build up a library of cutouts.

I have: outlet, switch and teardrop[xyz].

Let me know if you have checked it into any public code repositories!

Very nice model hotkey! I'm making one model myself. I'm having headaches getting the round edges and corners. I'm sure there's an easy way but all I'm doing is cutting a cube off the piece, then union it with a quarter of a cylinder. My code is long. I still need to do the corners with spheres. I wish I had a reprap, not possible now.

Rounded corners are indeed very nice AND very tricky. I didn't do them because the code gets too messy. An alternative would be to just slant the edges (by cutting off a cube in a 45
Â° angle).
I think for a "version 001" sharp edges are okay O:-)

Nice! Having the file downloaded and named as "C:\fakepath\chassis001.scad" is a bit strange, though.

Since I'm working from wihtin a VM the path may have been eff'ed up... My MakerBot-directory is mounted as a SMB network drive. This might have mislead the upload procedure into that funky "C:\fakepath". Again: Not my fault, dude!
