SDS MK4i Billet Wheel 3D printed Quick Change Tread

An untested version that has been requested..

A re-design of quick change TPU treads specifically for the SDS MK4i.  These are a ground up re-design of the Quick Change Formlabs WCP treads : 

The MK4i version has geometry adjustments to make them last longer, and be easier/cleaner to print. 
The grip on these is phenomenal, more than the Black Neoprene Tread Strip.  Our WCP design typically lasted an entire comp, with changes only for playoffs. 
 
Print Suggestions: 
Make sure to print them with the text right side up, as the model has angled cuts to ensure no overhangs above the screw head holes.  Print them at 0.25 layer height, and 5 walls (or 100% infill).  They print well taking the 0.20 speed profile, and changing they layer height to 0.25 (and number of walls).  If you have a drafty print area, add a brim, it will wear off on the first drive.
In Durability testing we have found that Priline's 98A TPU has the best wear characteristics:
