Prusa MK3 MK2s M10 Reverse Bowden

thingiverse

This is a reworked version of the JLTX Z toppers pre Taurus. I've only included the right-hand side, but if you use the mirror feature in your preferred slicer, it'll work out for a left-hand variant. You'll need an M10 pass-through pneumatic coupler, which can be found on Amazon. There's no requirement for supports, and there should be a super tiny stem supporting the one hole that appears to need support. Simply pop it off after printing.
