prusaprinters

I removed the existing collet hole spaces, slightly extended the back of the R3 back for clearance, and then added a simple design to hold the five threads for PC4M10 screw in connectors.Fusion 360 file included.  .3mf with painted supports for the threads also here.PrintingPrint in a vertical position.  Supports are not required; however, I strongly prefer to use snug supports (painted) to get a cleaner screw thread. I included a 3mf with that all set up for you. Use PETG, 20% infill, ,2 layer height, quality settings.  The pics show it being assembled with the MMU3 printed in Pusament PETG Orange. I use these adapters - https://www.amazon.com/gp/product/B01IB81IHGHere is the optional MCS larger system that I use behind this part  - https://www.printables.com/model/555238-mcs-multi-color-system-for-prusa-mmuAlso I made this which easily lets you add ball bearings to the MMU3 Spoolholders to replace the plastic wheels.https://www.printables.com/model/858747-ball-bearing-kit-for-mmu3-spoolholderVideo of this being used in MMU3 MK4 assembly -
