SMARS Robot Interlocking Tracks

These are interlocking tracks I designed for the SMARS Modular Robot created by Kevin Thomas (https://www.thingiverse.com/thing:2662828) and currently curated by Kevin McAleer @ www.smarsfan.com.

The original tracks were held together by small pieces of filament, which would often fall out during use. The new tracks have rounded prongs on one end which clip into rounded sockets on the other allowing the tracks to clip together in a chain.

In addition, I have slightly modified the profile of the tracks by slightly widening the grip and eliminating the end chamfers. This gives a bit more grip than the original tracks.
