Soft Tube Compression Fitting wrenches

I found the collars on watercooling compression fittings really difficult to tighten using thick zmt tubing, so If you have soft girly hands like me, you might like these thumb wrenches.

The short one is really optional, but it makes it so much easier to remove the collars without just having the whole fitting rotate. It works best if you use them as a push, thumb goes on the circular part and pushes. They're flexible enough to pop over the tubes while they're installed on both ends, and the plastic won't mar the fitting like pliers will.

Obviously be more careful not to over tighten because you can easily crank the collars all the way down with these and probably pinch the tubing too much.

STEP files are included for easy remixing. Will probably work as is for 1/2 OD fittings, won't work at all for 3/4 OD but I will probably make a version for those specifically later. You could also just scale it up or down in your slicer a bit for whatever fittings you have.

Just print them
