Mount for the EZstruder on the top plate of the Rostock MAX. I have been using this now for several months, and have even run Taulman 645 Nylon through it as well... All I can say is it's holds up great, is super low profile, and doesn't cause any issues at all! I tried to make the side walls thin enough it wouldn't take much material or too long to print. I used another thing (http://www.thingiverse.com/thing:119050) I created to make support triangle for the walls and motor mount. For wiring I cut a piece of 1/2" PVC pipe to the desired length, and cut out a "channel" for the wiring to exit early for the hot-end, and run all the way to the top for the extruderI used KISSlicer at 0.2mm, 2 perimeters, & no part cooling to eliminate layer separation. NO supports needed, but there is some bridging so don't go too fast For attaching to the top plate I used 30mm M3 socket cap screws & nuts, and for attaching the EZstruder I used to stock screws & nuts. I would recommend much shorter (10mm?) M3 screws, I just already had those on had lying around... I used this in conjunction with my top mount spool holder: http://www.thingiverse.com/thing:114717
