Hackaday 2019 Badge Case - Snap Fit

This is my weekend-designed case for the 2019 hackaday superconference badge.

Features:
* Room for cartridge
* Room for Add-ons
* Room for PMOD
* Hole for speaker
* Hole for IRDA

I've now printed this and it holds together fine. I chose 0.3mm layers with 0.6mm extrusion width except on the first layer 1.2mm and 5% infill. The prusa slicer 0.3mm draft defaults should also work fine.

Print both halves with the flat side against your print bed. You'll have to flip one of them in your slicer.

You'll need a zip tie through the hole in the corner to attach a lanyard. I didn't have time to do that better.
