Pre-grooved grindblock for Antony Pottiers Flat Frame (FR UFR Aggressive Inline Skate).
Modeled in Tinkercad.
Only one fit test print (with 20% infill) so far, so no real life tests yet. But the fit was good.
For use I'll print 100% infill with Esun PLA+.
The author marked this model as their own original creation.
