Thanks for this thing. Filament changes were often terribly annoying before, but now it's a snap if I need to get in there. Printed using PETG and the install was no more difficult than some temperamental filament changes.

I modified the design, but it's not worth claiming a remix. I didn't have magnets lying around so I printed a pair of 6mm height cylinders to just snap the pieces together after a little scraping and sanding. Maybe this will alleviate some people's concerns about magnets near motors. It feels secure, at least initially.

I ordered some 8x3 magnets and also some with a 3mm center bore to secure the fan side with 4 corners. If it works maybe I will post the remix.
