RUSH - Robo Ultimate Spool Holder

I liked the way the TUSH spool holder worked but need to modify it to fit the Robo. I added a curve to the part to fit the top enclosure and add both a spanner to fit a 1kg spool with a filament guide and some slot covers to hide the rest of the slot.

The spanner and the 2 sets of bearing holders all get tied together with #4-40 screws and nuts. The slot covers just drop into the slot and are mainly meant for keeping the heat in.
