Slingmobiles by artdavis

Slingmobiles are a collection of 3D printable simple wheeled toys that work with a printable slingshot track.
The individual mobile racers work well when assembled with M3 machine screw hardware (16mm socket cap screws and M3 Nyloc nuts). The nominal wheel rims are the 20mm diameter designs (though 25mm and 30mm are included as well for experimentation). Preferably the rims should be printed in rigid material (e.g. PLA) and then the tires in a flexible material (e.g. Ninjaflex) to be assembled together. Rigid one piece wheel parts are also supplied but these will have very poor grip on most floors and so will tend to veer around instead of traveling in a nice straight line.
Assembly instructions are included in the files. The slingshot assembly includes optional thru-holes and hex nut capture recesses for hardware reinforcement. Typically you shouldn't need them but if you start to see some layer separation (or your slingshot breaks) you can sure it up with M3 machine screws.
A handy printable M3 wrench to use for assembly is available here:http://www.thingiverse.com/thing:1174835
