This is a Better version of Anycubic Vyper spool holder (not the arm). It replace the Vyper's tiny spool holder entirely. This will secure filament spool so much better from fallout.
The simple version can be found in here https://www.thingiverse.com/thing:4909208, but needed to be fasten every now and then. This version is a "lock and forget" version.
ps. Thingiverse don't have Vyper as printer option, so I selected the Photon but it doesn't matter.
