Z Axis Reinforcement and +18mm elongation of Prusa MK2s

thingiverse

This is the mod I made for the PRUSA MK2S. I built a 1:1 clone almost two years ago, and after scheduling big maintenance not long ago, I thought to make it slightly less wobbly at higher speeds so I installed reinforcement rods. It may require changes in firmware, so if you experience problems, I can upload hex with the necessary modifications - PM me. Remember to adjust cables on the back of the X carriage to fully utilize this 18mm addition! Bottom parts connecting motor to the frame are actually a remix of the original parts: https://www.prusa3d.com/prusa-i3-printable-parts/ -------------------------------------- Similar to: Does not require any additional changes in hardware or software. @ +0mm with reinforcement: https://www.thingiverse.com/thing:3337357/ Does require small software change. @ +18mm with reinforcement: https://www.thingiverse.com/thing:3334944/ Does require extensive software and hardware changes: @ +30/33mm with reinforcement: https://www.thingiverse.com/thing:3337371 ---------------------------------- What you need: 2 pcs - 608zz bearing 2 pcs - m8x400mm threaded rod 2 pcs - m8x450mm threaded rod +8 pcs - m8 nut for the above *8 pcs - m8 washer (note that the outer diameter should not be more than 18mm) 8 pcs - m3x20mm 8 pcs - m3ns nylon lock nut din 985 185g PET-G (21% infill, 2 perimeters) 2 pcs - m4x40mm 2 pcs - m4x20mm 4 pcs - m4 nut ----------------------------------- | * - optional | + - at least that amount
