Safety Lock for Bambu Spools

Easy printable lock to prevent Bambu Lab's reusable spools from falling apart.

I found two other solutions here, but they were too hard to insert or too hard to remove.

This one slides easy into the gap and can be removed by hand.

Best printed in ABS/ASA or other high temperature filaments (for drying), but PLA will work, too.

No support needed, but I recommend slow printing for better stability.

Printable without brim, but please play attention to good bed adhesion!
