My tool box quickly becomes a disaster after any major projects. At best tools get yeeted back into their appropriate drawer, where they slowly migrate to a pile in the back of the drawer after being slammed closed. I had one drawer dedicated to bike tools, and this was mostly okay until it started getting piled full of various torx, triple star and E-torx sets… and then it became a mess too. After picking up a couple more bikes this year (n+1 am I right, lol), I needed more tools and decided it was time to model and print some custom holders. My collection of park tools felt like a good place to start as I was inspired to model some holders that could be shared, and park tool is pretty ubiquitous globally.
Let’s jump right in with some models. I have a .zip archive of them all together here, but feel free to grab them from my printables or makerworld page if that works better.

CT-5 Mini Chain Tool
This weird shaped chain breaker was a pain in my shallow tool box drawer. The handle kept getting rotating and jamming the drawer closed. But now its super secure and still easy to pick it up from the end of the handle!
TW-2.2 Beam Torque Wrench
This is definitely my favorite holder of the bunch. I ended up buying this torque wrench after destroying the SRAM UDH (Universal Derailleur Hanger) on the back of my Trek Rail. Apparently most click type torque wrenches are wildly inaccurate in reverse for left hand threads. Also somehow Trek uses a UDH that, uh, isn’t universal. Fortunately a local bike shop had the correct one in stock, along with this torque wrench. Unfortuantely, The trek UDH doubles as a suspension pivot, and was stuck in two carbon linkages. F’s in chat please. Using an automotive balljoint press on my carbon frame a week after buying it (used, at least) wasn’t a fun time.
Back on track here, this holder should help protect the beam from being knocked out of alignment. I’ve included two different style holders for the drive end, one with space for two 3/8”-1/4” drive adapters. Great for attaching those small 1/4” drive hex and torx bits.
FR-5.2 Cassette Lockring Tool
Probably the easiest holder here to model, I wish all Gridfinity holders were this quick to design.
BBT-18 Bottom Bracket and Lockring Tool
Pushing the limits of 42.0mm Gridfinity increments, you may need to avoid putting this next to tall bins, as its got a ~0.5mm overhang all around.
Printing Tips
These are all really simple parts to print. I use a bambu p1s, and have had good success with the default 0.2mm standard profile and PLA. If you want to save some of filament, changing the part to 0 bottom layers helps a bit. If you have an AMS or MMU, try adding some contrast by using the paint - fill tool in your slicer to make the interior of the part a bright color. Surprisngly it helps quite a bit when putting tools away to see the bright spots where a tool is missing.
Best of luck in keeping your toolbox from becoming a mess like mine. If you liked these models I’d appreciate it if you left a review on the printables/makerworld pages, or even uploaded a photo of your own prints.
