1968 Mustang Reverse Lockout Knob Bushing

prusaprinters

Apparently it's pretty common for these to break/wear out and nobody makes replacements.  Instead you have to buy a whole expensive shifter assembly.  The stock bushings are pretty anemic and there's lots of room so I made these longer and thicker for a better fit, smoother operation and better durability.  Given the application I printed these in Overture Nylon filament which is decent stuff.  On my Prusa MK3S I used the Taulman Bridge profile modifying the bed temp to stay at 90c with a little glue stick on the bed to help with adhesion.  The nylon does shrink a lot which required scaling up the print to 104% in the slicer to compensate.
