Despooler stopper

This is designed for the A1 without the AMS. The 3MF file has two plates - one for rigid filaments (PLA, etc.) and the other for TPU. The difference: TPU has a solid sleeve that should be cut with scissors so it pops over the support. The one for rigid filament is in two pieces, a guide and a clip to hold it in place. Both are a lose fit on the support and designed to drop down into the spool.
