MK3/MK3s X idler with tensioner

thingiverse

I'm intrigued by the idea of stock design and yet I have to admit that stock tensioner leaves a lot to be desired. So here's a solution for you. This setup is fully compatible with your stock x carriage. Here are the parts you'll need: - A stock idler sourced directly from Prusa Research - A compatible shaft that measures Ø2.9-2.99mm in diameter and 15-16mm in length - Two M3 nylon hex nuts - Two M3x18 socket head screws
