This is the most ridiculous modular wrench holders set with 16 sizes to snuggly fit every wrench I have. Unless you also have crazy OCD and need every size to fit perfectly you can probably get away with just printing the medium and large. There is a correct holder for everything from tiny full polish 6mm to 80s craftsman chunky 1-Inch box wrenches and everything in-between.
Most of the wrench holders i've seen are either one-size-fits-all or fixed wrench count neither of which worked for me.
The individual wrench modules snap together with double taper interfaces so you can fit a set of two or 32. Get a new wrench just seperate the rack, insert a new holder, and snap it back together. The rack is secured in the drawer using two magnets per holder so they do not slide around even if the drawer is slammed shut.
For this set, we started with 8x8x3 disk magnets for the larger sizes and 10x5x3 for the smaller ones, but once I ran out of 8x8x3's we made some alternative versions of the bigger sizes using the 10x5x3's so both versions are included.
Lastly to complete the look we designed and printed end plates (front and back) to finish the sets with a clean look.
