Prusa i3 Mk2S Extended y-belt Holder

thingiverse

This solution provides a quick fix for those who have mistakenly purchased the Prusa Bear Upgraders' Mk3 frame instead of the intended Mk2.5 frame. The Mk3 frame boasts a 20mm longer y-axis compared to the Mk2S/Mk2.5 frame. Using the Mk3 rod holders with Mk2.5 parts will cause the y-carriage to collide with the y-rod holders before the y-axis end stop is triggered. I have modified the y-belt holder, available at https://github.com/prusa3d/Original-Prusa-i3/blob/MK2S/Printed-Parts/stl/y-belt-holder.stl, by adding 10mm to its length. This modification should allow it to hit the y-axis end stop. To implement this fix, simply use the Mk3 rod holders and a 106mm spacer along with all other Mk2S/Mk2.5 parts. Please let me know if this part functions as expected or if further adjustments are needed. Note: Be aware that the Mk3 frame stands 3mm taller than the Mk2S/Mk2.5 frame, so your z-tops may not sit flush with the top of the frame.
