Bambu Spool Weight .375 Bearings.

BAMBU SPOOL WEIGHT 3/8" BALL BEARINGS The weight is made for Bambu Labs spools with a 55mm diameter (54mm OD) and fits a spool width of 62mm to 70mm. The weight was designed with eight tubes with seven 3/8" ball bearings per tube. With a total of 56 bearings, the spool holder checks in at right around 233g fully loaded, 142g half full, and 53g empty. The weight is adjustable, but I would try to balance it by using only 4 of the eight tubes. It fits my Polymaker spools as well, and it may fit others. The pass-through hole was mainly to minimize material and print time, but it may be helpful for some. The hole is 14.75mm or 5.8" ID. The thought process behind the design was first to minimize the sound of free-floating bearings rolling around. Second, to reduce print time and materials, form follows function. I had no used batteries lying around, and the bearings looked relatively inexpensive. Specifications used: Bambu Labs X1C Bambu PLA Basic ( Do not over-tighten if PLA is
