Prusa i3 MK2 and MK2S : Y Axis corner block replacement

thingiverse

Update 15 March 2017: More update coming for MK2S version. Update 30 Oct 2016: Work in progress continues with removal of rear block due to a flaw in design and dimension. Update will be posted soon. Update 7 Nov 2016: Design completed, I have printed but yet to install it as I am waiting for my motor damper. Update 8 Nov 2016: Installation completed, final fine alignment is done by tightening the prints (compression). The Original Prusa Mk2 kit is notoriously hard to build and extremely difficult to align. It's assumed that a well-aligned printer will be quiet and have less uneven wear on your bearings. This modified Y-axis block is designed as a drop-in replacement for the "Original Corner Blocks." All files are version 5.0. Print time per block is approximately four hours. Front blocks take around three and a half hours to print. Rear blocks require about four hours. Y motor mounts can be printed in one hour. Optional 100mm Left Z to rear takes just over half an hour to print (0.5 hours). 80mm Right Z to rear also requires 0.5 hours to print (optional). Advantages: This modified block can be used with LCD without any issues. It's a drop-in replacement that uses fewer nuts and bolts. Ideal position for Y motor mount is achieved with this design. Works with damper or without damper motor configuration (just need to offset pulley). Compatible with IGUS RJZM-01-08, which has a diameter of 16mm (1mm bigger than the default lm8uu). Easier way to make PRUSA perpendicular. Some tips for squaring the printer can be found by watching this YouTube video: https://www.youtube.com/watch?v=4KgG3XVU5so Note: Motor mount requires two nuts and a washer to compress against rear block. I printed my design at fast speed, so some areas required sanding. Credit goes to Aaron Yourk and Joseph Tam for their input and inspiration. Aaron also made a remix of this design: https://www.tinkercad.com/users/7Z01p6EVg8r-aaron-yourk Print Settings: Printer: Original Prusa MK2 Rafts: Doesn't Matter Supports: Yes Resolution: 0.3mm Infill: 20% Notes: Perimeter Shell is set to 5, and Top and Bottom Layer is set to 3
