CNC Bits and Collet Holder
thingiverse
I designed my first CNC bit holder (www.thingiverse.com/thing:4249121) and then quickly realized that I needed a spot for various ER11 Collet sizes that came with my SainSmart Genmitsu CNC Router 3018-PROVer. Any maker worth their salt would want to design/print their own, plus there's no spot for the collets! You can buy a bit holder from Sainsmart but. A few hours later after getting reacquainted with Fusion 360 changes, I had a nice little CNC bit and ER11 Collet holder box. I recessed the first 30 holes (from the left side) enough for standard Nano blue coat bits, but the last 10 are 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. Be sure to flip the magnets on the opposite side for correct magnetic attraction. A little E6000 adhesive and the magnets never moved.
