Low Profile LM8UU X Carriage (Makergear)

In a nutshell, this was designed to accommodate an E3D hotend who needs to hang down a little further than most due to the heatsink and fan. To do this, I slimmed down the platform itself and then moved it downward so it was near flush with the bottom. The revised carriage is the orange part.

This is, as the title suggests, for the Makergear Prusa from yesteryear. It will not support modern extruders. This seems problematic, but I have been very well served by the original extruder so I don't intend on changing it at the moment.

The LM8UU bearings simply slide in. I epoxied mine in place and I'd recommend you do something similar. Epoxy is pretty cheap, easy to use, and strong as heck - it just has a bit of a smell for a couple hours ;)
