CNC Bits and Collet Holder

Version 2.0

I designed my first CNC bit holder (www.thingiverse.com/thing:4249121) and then quickly realized that I needed a spot for the various sizes of the ER11 Collets that came with my SainSmart Genmitsu CNC Router 3018-PROVer. You can buy a bit holder from Sainsmart but any maker worth his/her/their salt would want to design/print their own. Plus there is no spot for the collets!

A few hours later after getting reacquainted with the changes in Fusion 360 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 the 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 the correct magnetic attraction. A little E6000 adhesive and the magnets never moved.
