Bobina Bambu Lab Mini Spool + extra ring for AMS

spool created from LIAO1MING https://makerworld.com/it/@YM4025 go check out his profile! I printed these spool to fit inside the bambulab boxes, but I realized later that these spool could not be used for ams, so I designed an extra ring that allows it to be inserted without the aid of glue, and that works perfectly for ams!
