Prusa MK3/s X-Axis R4+ with full tensioner

thingiverse

UPDATE 18/08/2019 It's better to replace the Prusa pulley with one that has two bearings, because the originals will start to wobble when changing direction. I buy these parts in W6mm, 20T, Bore 3mm, Toothless: https://www.ebay.de/itm/5x-GT2-2GT-6mm-10mm-Riemenscheibe-Bohrung-3-5mm-Zahnrad-Pulley-3D-Drucker-CNC/153219305193 I have equipped the Z-slides of my MK3/s for Prusa with a belt tensioner and a clamping function for the liners. This project is based on "Revised X-Axis (Prusa I3) by vekoj" but is not a direct remix. The engine holder is based on the original R4 from Prusa, has been extended only in design and of course in the function, and the counterpart now the tensioner also, but with some components from several different projects. This kit is absolutely compatible with all other Prusa MK3 and MK3s parts of the R3 and R4 types. No other parts need to be printed. These adhere absolutely to the original measure of Prusa and can be used with the original X-Axis sled! That was the aim of this project, furthermore, it was tried to build everything so that no additional parts had to be procured, only a 13mm M3 countersunk screw is needed to screw the pulley into the tensioner. To fit perfectly with a few other R4 + parts that I have used in my MK3s conversion. See -> https://www.thingiverse.com/thing:3811614
