I have nylocs on top through the bed, I could flip the bolts over and put some knobs on. The bed doesn't have a counter sink for the bolts for a hold back thought. I'll give that a try anyways!

It's a rebuild of the Prusa I3 I believe, most info can be found at the REPRAP wiki : https://reprap.org/wiki/P3Steel#:~:t...oza%2C%20Spain.
Here's the link if you want to take a look.

I built it over a couple months using the parts list on that wiki on my own, no kit.
