Prusa Mk3S Y-Axis Bar Holder without zip ties

thingiverse

The Y-axis on the Prusa Mk3S is held down with zip ties. I really didn't like looking at those (although they do seem to work fine) so I measured the Prusa part and created a new clip to replace them. Since I was replacing them I also used Ruthex 3mm melt-in inserts instead of captive nuts because a) they look nicer, and b) I had them to hand. Spring fit on the bar, so you have to insert the bar into both end holders **before** inserting the bar into the printer. This is a different assembly order than in the manual. Credit for the original part to Prusa: https://www.prusa3d.com/prusa-i3-printable-parts/ NOTE: these require 14mm bolts in place of the existing 10mm ones. NOTE 2: Prusa has redesigned this part for the MK3S+ so this might not be relevant to anyone else. NOTE 3: I also since discovered these https://www.thingiverse.com/thing:3305218, they achieve the same but use captive nuts instead. Almost like a cosmic confluence remix or something. Oh well.
