Prusa Multi Material (MM) brackets for overhead filament spool feed i3 MK2s

thingiverse

Brackets + pulleys to allow overhead filament spool feeds (eg from here: https://www.thingiverse.com/thing:1332025) to be used with the Prusa MM kit (which expects the spools to be behind the printer). These parts use the bearings and aluminium tubes supplied with the MM kit, intended for the spool holder assembly. You will need to print a pair of brackets and 2 pulleys for dual material and 2 pairs and 4 pulleys for quad material MM printers. Holes in brackets for the filament to pass through before it goes around the pulley and into the extruder feed. Square M3 nut needed in slot of each bracket and ~30mm M3 screw to secure (4 of each needed). Original bracket design borrowed from: https://www.thingiverse.com/thing:485438 Support needed on pulleys and around nut hole.
