Based on MrFlippant Original Idea and design of the MSR Tire Truer Sanding Plate Reciprocation Machine I made it work for the Overdrive tire truer RSM4.
I have printed everything in ABS on a Voron Trident
I have used the recommended Voron settings of for most of the parts as the extra walls seams better for the parts that thread into ABS
Layer height: 0.2mm.
Extrusion width: 0.4mm, forced.
Infill percentage: 40%
Infill type: grid, gyroid, honeycomb, triangle, or cubic.
Wall count: 4.
Solid top/bottom layers: 5.
Supports: NONE.
The Axle Pulleys I printed at Layer height: 0.1mm and 100% or Solid Infill and random seam.
I have been working on this since November 2022 so its a bit hard to remember all the changes I have made.
I have also added some other parts:
Thumb Screw for easy tool free changing of the Swing Arm
Sanding plate guides with Thumb Screws for quick and tool free adjustment.
Custom size Axle Pully so the Sanding Plate gets more throw.
Large Knob for the Hight Adjustment of the Swing Arm
Gantry (Motor Mount) can have a switch added.

3mm and 2.38mm reamers for the pulleys.

The author remixed this model.
I have used the following and modified them
Gantry (motor mount) - I added a switch mount and hidden wire channel, moved mounting point.
Motor Arm - I added a M3 lock nut and changed the length to suit the amount of throw needed to use most of the sanding plate.
Link Arm - Changed Length
Sanding Plate Mount - Changed Length
