About this 3D model

Increased PTFE tube holes by 0.1mm based upon feedback. I changed the mount points on the inner plate to use M3 threaded inserts. I slightly increased the M3 holes on the outer plate so the screws can pass freely. Finally, I increased the diameter of the tube hole by 0.1mm (it was too tight for the PTFE tubes on my printers). Hardware: Four M3 inserts with 4.6mm outer diameter and 4mm length.
