Description

Dumbbell bar wrench that fits most star-lock nuts on 1 inch bars - no more rattling weights! Makes tightening and loosening star-locks a breeze! Print with lots of outer walls for strength. 3D printable replacement nut is included with model on the 2nd sheet.

The dimension across the star “lobes” is 2-¾". If your star-locks are slightly different in size the entire wrench can be scaled to make them fit.

The included nut will fit a 1"-4 TPI ACME threaded bar.

That's unfortunate that it was too small! I will update the model description to show the dimension across the the star "lobes" and add details about the nut as well. You may be able to scale it up slightly to make it work.
