Prusa i3 MK3/S/+ printed Y-ends

thingiverse

UPDATE: added a split version of the rear Y end, which includes the Y motor mount as well. This version fits on smaller heatbeds. The one-piece rear version fits the Prusa MK42 and MK52 heatbeds, just rotate it by 37 degrees. I've designed 3D printable Y ends for the Prusa i3 MK3, MK3S and MK3S+ printers, which is based on the same concept as the Y ends for the Prusa Mini. As I haven't printed these yet, it's marked as work in progress. You will need two M3x16mm screws for securing the Y idler mount, the rest of the components (Y motor mount, LCD mount) have countersunk holes, so the original M3x10mm screws will fit. The M5x16mm screws holding the 3030 extrusions are long enough to reach through, alternatively you can substitute them with M5x20mm ones. The Y linear rods are held in place by zip ties, like on the earlier versions of the printer, however I still recommend sliding them in from from the end of the parts, instead of pushing them in from the top. Also, you will have to mount the Y rods earlier, than the original assembly manual suggests, between steps 8 and 9 of the Y axis assembly manual: https://help.prusa3d.com/en/guide/2-y-axis-assembly_165795
