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!

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

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