Magnetic Compressor Tool Holder

Tired of my compressor accessories constantly cluttering up my workbench, I decided it was time to come up with a better storage solution. Tools like my digital pressure gauge, air blow gun, and other small pneumatic accessories always seemed to end up buried under something else. Normally I would just mount holders on the wall, but working out of half of a one-car garage means wall space is already completely occupied by other tools and storage.

Then it hit me — there was plenty of unused space directly on the air compressor itself.

So I designed this magnetic compressor tool holder and printed it on my 3D printer. The holder uses 1-7/8" block magnets, which I happened to already have from a Storehouse magnet assortment purchased at Harbor Freight (see link https://www.harborfreight.com/ceramic-magnet-assortment-16-piece-58066.html). From what I can tell, these are fairly standard-sized magnets that can also be found online through places like Amazon.

The magnets are secured into the holder using CA glue, which provides a strong and permanent bond to keep them firmly in place during everyday use.

Originally, I hoped the magnets would be strong enough to hold heavier pneumatic tools such as brad nailers. While the magnets do grip well, heavier tools tended to slowly slide down the side of the compressor due to their weight. However, for lighter accessories such as digital pressure gauges, blow guns, air chucks, and similar small tools, this holder works extremely well.

The tool openings are intentionally designed with a snug fit at the entrance. Once the tool is inserted, the holder slightly opens up internally to better accommodate the tool body. This helps prevent tools from accidentally getting bumped or knocked out while in storage, while still allowing them to be easily removed when needed.

This design keeps frequently used compressor accessories organized, easy to reach, and off the workbench without taking up any additional wall space.
