Hoverboard motor track system

Hi! This is a track system for a hoverboard motor. I used ABS for most of the parts, and TPU for the road pads for more grip. (white parts). I have an hour or so of run time on it and it has held up well.

It uses 2 mm steel rod for the pin connecting links, and heat set inserts into both sides of the track link to hold it in. Small M3 screws secure the pin. The track pad is attached to the track link with M3 hardware - there is a pocket for the nut on the back side of the track link. 

The idler wheel uses 608 bearings. You need a type 1 and type 2 idler, they are not identical. The sprockets used an existing sprocket OpenSCAD library - reference in source. The track design is very heavily based on this one: https://www.thingiverse.com/thing:3112734

The track system showed no problems with coming off. It uses 25 links per track in the configuration tested. 

I found it worked well but would sometimes stall when trying to turn in place in grass. I'm not sure if this is a limitation of the hoverboard motors or the RioRand motor driver I'm using.
