Z top spacers for Prusa i3 R2

thingiverse

A Major Refinement for the Prusa i3 R2 by Nicola P. Nicola P makes a strategic improvement to the classic printer design with an enhanced build that leaves nothing behind but precise quality control in place of any sloppy mechanical movement due to over-specified tolerance, all while avoiding common Z-M6 rod jam issues by keeping those smooth and slippery Z M6 threaded rods precisely where they need to be – securely fastened at a stable constant distance from the equally robust Z smooth bars that guide their movement smoothly along three dimensions, never wavering. To put it bluntly, these expertly-crafted upgrades boast longer than average original threads so that adjustments are a cinch: install them once you have achieved ideal performance out of those precision-crafted bearings, and bolt 'em up good and secure – we're talking solid. Using 2 reliable ZZ606F high-tolerance bearings for precision movement in tight spots and M6 hardware keeps things sturdy but also minimizes material usage – an upgrade fit for even the most discerning user. Now go build a beast with more oomph than before: make some quality time spent designing your future Prusa i3 R2 projects count, get creative!
