Zero friction filament holder for Anycubic Mega S
Description
At some point I was not satisfied with a filament spool holder of my Anycubic Mega S - it was too much friction there. So I did a quick design of a simple attachment based on conventional 608 bearings, which are cheap and are used everywhere - skates, inline skates, motors etc. I first thought to design something to replace the original metal bar, but it is hold with only two screws from one side only, so putting 1kg spool there seem to be a bad idea. The holder is placed on a native filament holder and fixed with two zip ties. Size is small enough to enable positioning of spools having just 50 mm (2'') opening. The 608 bearings should be put on a shaft and limited with a ring from another side - that allows to avoid bearing rubbing the main part. Repeat for the second and put both inside the main part. Works like a charm from a first print :) Ok - not from a first one - I have redesigned the model to have rounded edges, but the printed already part was violently adjusted by a knife.
