About this 3D model

Two Bambu spool plates cost 4.88. This adapter weighs about 40g and takes 57 minutes to print. It's much more cost-effective than printing a whole spool holder, which takes 4 to 5 hours and consumes hundreds of grams of filament, isn't it? P1S+ Bambu PLA-FS prints it perfectly. You can fine-tune the STEP file according to the shrinkage rate of your filament.
