lego tank tread

needed a tank tread for my sons latest build.. and he was short a couple of the pcs.. so I drew it up after trying one that was on thingiverse that just wasnt working out.

after about 8 attempts to get the clip portion right.. I think I got it to a point that we can use it.
if you use higher detail and smaller nozzle.. (I used a .4 and medium detail to get it done quicker)
