Collapsible spool holder with bearings (Anycubic i3 Mega)

thingiverse

There are plenty of spool holders, but none quite like this one for the Anycubic I3 Mega. It's over-engineered, perhaps, but that's not necessarily a bad thing. By remixing the plate part, you can use it on other machines as well. The spool itself is designed to be free-running. Since I have another machine with great holders, I decided to adapt its design. To make it more versatile, I made the holder collapsible. When collapsed, it won't add any width to the printer. To build this spool holder, you'll need several parts: a plate, a round mount, an angular mount, and a dome. The dome fits into the angular mount, while the round and angular mounts fit together perfectly. You'll also need two LARGE_SPOOL_MOUNT.stl files for holding the actual spool. In addition to these main components, you'll need some extra parts: two M8 x 70mm screws, four 8mm unsealed bearings (type 608), six M8 locking nuts, two 8mm steel balls, two 25mm x 6mm springs, two M3 x 10mm bolts, eight M3 x 25 bolts, and finally, eight M3 nuts.
