Maker Beam Spool Holder

thingiverse

I made this so i wouldn't have to reach behind my Ultimaker to change the spools. it uses a quantity of 4 - 4mm ID 12mm OD and 4mm thick ball bearings. i used 4 extra tall melt in 4mm threaded brass inserts in the axle pieces. there are also 8 4mm flat washers. the aluminium extrusion maker beam, i order it direct from here: https://www.makerbeam.com/ i also printed, but didn't use the body piece, it doesn't seem necessary, but i included the model in case anyone wants to try it out.
