3D Printed Modular Magnetic Wrench Holders

Continuing with the shop organization new years resolution today we are looking at a new design:

Modular Magnetic Wrench Organizers.

A few weeks ago Jess and embarked on a project that I had been wanting to do for a while ago. Years ago I sketched up an idea for a modular wrench organizer but at the time I did not have a 3D printer and making them out of materials available at the time proved to be troublesome. We started playing around with designs again. Jess having just worked on some bit holders to interface with a Dewalt case copied the double tapered friction connectors to this design and we started printing prototypes.

Wrenches come in many sizes and any given set I own has small thin and big and wide handled wrenches. Most of the holders we tracked down are simply one-size-fits-all which really didn’t work for me. From my late 80s craftsman sets to the Husky and Hazard Fraught full polish sets we ended up with a wide assortment of sizes to snuggly fit every wrench.

Lastly to complete the look we designed and printed end plates (front and back) to finish the sets with a clean look. I plan to eventually print these end plates in colors to identify SAE vs Metric, but for now, they are in separate drawers.

The individual wrench modules snap together with double taper interfaces and are secured in the drawer using two magnets per holder. 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. And because I had a couple of finicky wrenches that didn’t sit quite right in the tapered holders there are a couple of oddball sizes included to make sure everything fit just right.

You can even assemble the “set” then print them all at once 🙂

Lastly to complete the set we also designed and printed 2 sizes of ignition wrench holders.

Description for Thingiverse:

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 separate 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.
