Adjusting the leveling bolts on NTRAK and TTRAK modules sucks. Adding some printed knobs makes it far easier. These are those knobs.

Even thought TTRAK modules are far easier to adjust the height of than NTRAK modules because they’re not on the floor, the limited clearance under the frames still makes it a challenge. You can’t quite get your fingers under there to get a hold of them. Adding something that gives you a better grip makes this a lot easier.

I spent a few minutes in TinkerCAD and whipped these up.

Print these up on your favorite 3D printer, and slip them over the bolts under your module. Once installed they make grabbing a hold of the bolt much easier, and even better, allow you to just roll your finger along it to adjust them up or down.

You can access the drawing here on TinkerCAD or just download the STL files (one for 1/4-20 bolts and one for 10-24 bolts).
