Spool Wight GST3D and Bambu Lab

i designed a real simple gut effective spool-wight for my GST3D Spools. i desguned it for useing it in my BambuLab AMS. it is desinged to not fall out without opening it. it works also with BambuLab Spools, there it can through the center-hole , but also working great. there is space for 5AA and 1 AAA Batery , or whatever you wanna fill inside. also on my Printables: RainerBavaria | Printables.com
