These were quickly created in V-carve to hold my bits and tools. I leveraged a bit of the design form past users and created my own.
This stores the clamp kit from Inventables in one block and several types of bits in the other block. I love this wrench I ordered on amazon for my DW-611 router since the original was lost.
