prusaprinters

Custom Y-axis ends for MK2/MK2.5/MK2.5S printers. Stiff and with belt tensioner - no more hassle with loosen belt or X/Y axes not being perpendicular. Based on great design by @pcky https://www.printables.com/model/135834-prusa-i3-mk2s-mk25-y-axis-upgrade and remix from @matthewlegates https://www.thingiverse.com/thing:4791446 LCD supports (standard MK3 type) included - modified for hex nuts instead of the square ones. EDIT: Added another version of LCD supports - for compatibility with replacement LCDs (as mine from AliEx has larger contrast pot that doesn't fit the holder) What you need:3x M3x18 screws for the y-axis stepper motor4x M3x20 screws and 4 hex nuts for the LCD supports2x M3x20 screw and 2 nylon locking nuts for the tensioner16 mm shaft for the belt tensioner pulley - cut out of a M3 screw  Y-axis front and back:PETG0,20 layer thickness15% grid infill7 perimeters5 top and bottom layersno supportsI printed the tensioner pulley cover with brim, but it shouldn't be necessary Tensioner and LCD supports:PETG0,20 layer thickness15% rectilinear infill2 or 3 perimetersno supports
