MakerBot Mini Gantry Support

I was given a MakerBot Mini, and one of the first things I noticed was how weak and flexible the support that holds the gantry that the Smart extruder clips on to was. Horrid little plastic recess, that slots around a metal plate. It all wears and gets weak and allowed the print head 5mm or more freedom to slop around in the Y-axis.


This is two part and requires 4 extra screws and drilling through the black plastic casing with a 2.5 or 3mm drill bit.

Screws closest to the front of the machine are 3mm x 15mm and the others are about 8mm.

both countersunk to all the heads to pass underneath the X-axis bump stops.

Might need a little bit of further tweaking so I have included the Sketchup Files too.

You need to pop off the Extruder, then move the gantry to the front to give clearance to get a Torx driver in to the two screws that hold the gantry to the metal plate.
A slightly smaller Torx driver takes off two screws in the body that allows the catches to be popped and
