Linear rail for Prusa i3 Bear upgrade

Those are the parts I'm using on my Prusa Bear upgrade...
I'm trying to re-use the U bolt concept.

Liquid plastic adhesive UV.

After you printed the 3 spacers, you have to modify the 6 flat socket cap screws with a File as in the pic.
Place the screw as in the pic and glued it, please to be sure it's well glued.
The glue don't have to come out from the holes.
All the screws have to be perfect in it, the screw's head don't have to touch anything.
Attach the spacers on the blocks, place the carriage and then lock it with the Nylon Hex Nut.

The instructions are complete because I'm doing a Step-by-Step Guide with photos.
