700gr refuel spool with meltingnuts

hey there,i wanted to use my ordered refill filament in 700gr packs….i tried to use some existing spool models but everyone failed…so i started at zero to deslgn my own… and after several iterations now i have a working one i want to share with you. focus in design was quick producing with less filament. -its tight enough to use it without respooling (for the ams it is...lets say: ok, but respooling works better - and i have designed another one with small teeth with is working much better in the ams system)-quick load and unload with cable ties-you need 3x M5 meltingnuts an 3x M5x50mm cylinderhead screws i hope its also usefull for you…let some comments and llkes!. O.M.
