Prusa thin x-carriage for snap-in LM8UU by ohnoitsanengineer Dec 16, 2012

Description

This is a quick design I drew up for a Prusa X-carriage. It's fairly thin, and should have all the proper mounting holes for most "Standard" extruders (gregs/wades/etc). Originally I made this to work with my non-standard extruder, so I modified the files to allow for standard mounting, so that others can use it. For added stiffness, there's four #8 socket head cap screw counterbores, for attaching a stiff plate on the bottom, or a fan, or whatever you want.

Designed in Solidworks 2010, and CAD files are attached.

Instructions

Download, open up in your program of choice, and print! (hey, forgot to publish this one. it works, but it's a bit flexy if your extruder spits out a lot of pressure.)

NOTE: you may have to rotate the model around a bit, Solidworks' Z axis is not in the same direction as Replicatorg or other programs. The LM8UU holding flaps point upwards, but you can probably figure that out.

This should snap right into a standard (50mm rod spacing) setup. If you want a more permanent solution, stick a piece of wood, metal, carbon fiber, or anything stiff on the bottom and bolt it into place. This will ensure that the bearings stay fixed, and you won't get any wobble.
