Y Axis Bed Bearing Holder for stock Prusa MK3
thingiverse
Remixed from [Sasha Zbrozek's Y bearing holder](https://www.thingiverse.com/thing:2984280) for Prusa MK3. I made some adjustments to fit my needs better. His design work great for bear frame MK3 but not quite as good on my stock MK3 frame. My changes: * Remove slots at bottom for M3 nuts (the nuts don't work with stock frame). * Adjust heat-press insert holes to work better with the heat-press inserts that can be [found on amazon with free shipping](https://www.amazon.com/gp/product/B07BDG4JR6/ref=ppx_yo_dt_b_asin_title_o00__o00_s00?ie=UTF8&psc=1). * Slightly thinner outer shell for less chance at it bumping stock MK3 frame. * Increase hole diameter for screws from 3mm to 3.20mm to account for shrinkage after print, and also the heat press inserts will be holding the screws so no need for the screw holes to be tight. This make less chance of the heat press inserts popping out. Again, thanks to zbrozek for amazing design and providing the files. This is much better than the stupid metal U-bolts that hold the bearings onto the bottom of the bed on stock MK3.
