Spool Adapter Sunlu 250g

After many trying and errors, I developed an adapter for small spools. This model is designed particulary for the 250g Sunlu PLA spool, but probably also fitting to other brands with internal diameter ~52 mmThe 3 mm thickness of the rotors are allowing a smooth rotation in the Bambu AMS without any scratch. Every adapter comes as 2 separated halfs , a positive (with screw) and a negative (with thread) Note that there are 2 verions of the adapters:1) with knob (K+) helps the adapter to rotate the spool entering precisely in the existing holes from sunlu spools.2) without knob (noK) can be used also in similar sized spools According to your spools and experience, you can combine the adapters as follows (all personally already tested):K+/K+K+/noK noK/noK Printed with ~45g PLA, 0.4 noozle, 0.28 layers and 15% filling. Have fun :D
