About this model

These are custom MK3 style y axis ends for my fresh upgraded Prusa i3 MK2.5. It's super stiff so it won't bend by the tension of the y belt. Best printed in PETG with 20% infill. You will need to print the MK3 LCD supports as well in order to mount the Display to this front. There are two small rings around the big holes for the threaded rods. While printing, they support the inner hole and should be removed before mounting the parts to the printer.
