Solderless (*) DIY SlimeVR tracker

Custom case for my DIY SlimeVR trackers. The main tracker sits in a 3-part box with a variety of ways to put a velcro strap or other attachment through it. The electronics all come from Adafruit.

* No soldering is needed on the main tracker. The optional aux tracker needs one little dot of solder to set the address of the second IMU.

Photos might show a slightly earlier draft with fewer slots for straps. The OpenSCAD files are included so you can modify to suit your parts and mounting needs.
