Mini Spool Adapter for AMS

I have bought an Anycubic Kobra 3 Combo. I still had a few 250g filament spools lying around and couldn't put them in the AMS because they were too small.
That's why I designed this adapter spool.

Printing works perfectly. There are also no problems like with the cardboard spools, where the edges are worn off and then the spool no longer unrolls.

The adapter can be used with various printers. It is also very suitable for rewinding.

There are 2 versions. One with a pin (so that the small spool does not slip) and one without.
