Gridfinity Dremel Sanding Band Holder có Nam Châm+ 1x4x8

Sanding Band holders of 6 Large, 2 Medium, 6 Small sizes.  

I shortened it by 1 unit to allow more flexibility of vertical or horizontal orientation in the dremel box, and because medium sanding bands are rarely included in kits. 

Re-added magnet holes with square bridging method to eliminate fallen rings. Optimized for .6mm nozzle and .28mm layer height (higher resolution should print fine). 

53mm total height  (8 units would be 57.8mm with stacking top lip).
