These are NOT required for sensorless homing. These are just part optimization for use with sensorless homing. My goal was to preserve as much of the original parts as possible ,like the internal ribs inside the TAP center, for compatibility.
V2 update: One of the belt holders on my TAP snapped (possibly do to some experimenting). It broke by the top hole so I beefed it up a little.
The author remixed this model.
TAP Center V2:
With the Tap piece I simply cut it in half and mirrored the other side. Its been working great on my Trident and was fairly simple to make. I also beefed up the area above the top mounting holes.
XY Joint:
This simplifies the model for easier printing and better strength. To fill the gap, I mirrored the left side and projected the geometry to make the area for the wire path. No other modification was made. The curve in that spot mirrors the Left side and should have no issue with compatibility.
