Universal Spool Weight for AMS

Scaled up z-axis to fit better in my spools (Bambu, Overture, and Polymaker verified). Modified small screw portion on battery cover to have 100% infill to alleviate snapping off when assembling (read about this issue in the comments) . Also, added supports to inside of large compartment to give cleaner look and some brim ears to help support the very small surface area on the larger parts. Worked well on my PLA test print, as well as my final printing in ASA. Single, double, triple, and max build plate (four) options for printing however many you need. Cannot confirm fitment of AA batteries, however they should fit fine, as I opted to use ½"(13mm) ball bearings, available on Amazon or other platforms. For some reason the bearings listed as ½" are significantly cheaper than ones labeled 13mm. Two hundred ½" bearings were about 25 USD, twenty 13mm bearings were about 10 USD. Can't explain that one, but that's what I found. Four fit nicely into each single battery spo
