Filament dumbbell

one day i was wondering to myself “would that work”, and yes it does,this fillament dumbbell can hold 4 spools, if you use bambulab spools you will get around 6.75kg (14.88lb) because their spools weigh around half a kg and 4 full rolls if 4kg, its not too much weight but also i did not want to make something that big.this should fit any spool with the center inner diameter of at minimum 55mm, the same as bambu labs.cardboard spools can fit tight but be carful when taking them off that you dont break them.Tested spools:bambulab: fitsElegoo: fitsSunlu: fitsCreality ender PLA: fitsEsun: fits3d printed bambu spools: fits.elegoo TPU: fitsBoost Meplease boost me if you enjoy any of my models, it shows me what people enjoy more as well as it helps me bay off the expensive filament.
