CNC Bits and Collet Holder

thingiverse

Human: Version 2.0 I crafted my first CNC bit holder, accessible at www.thingiverse.com/thing:4249121, then swiftly understood I needed a place to store various ER11 Collet sizes that came with my SainSmart Genmitsu CNC Router 3018-PROVer. Anyone can purchase a bit holder from Sainsmart, but makers worth their salt design and print their own. Moreover, there was no spot for the collets. A few hours after relearning Fusion 360's changes, I created a compact CNC bit and ER11 Collet holder box. I drilled thirty holes (from left to right) about 30mm deep to accommodate standard Nano blue coat bits, while the last ten were only recessed 15mm for V-shape bits. I used MK3 x 2mm magnets in each corner on both halves of the box to secure the lid to the base. It's crucial to flip the magnets on the opposite side for correct magnetic attraction. A little E6000 adhesive was applied, and the magnets never moved.
