In order to protect my wrists during push-ups, I quickly designed these push up bars (Parallettes).
The broomstick, i had lying around, has a diameter of 28.35mm.
The hole diameter of the 3d model is 28.2mm. I used a rubber mallet to attach the 3d printed parts to the wooden rod.
No screws are needed.
There is a test ring to check the tolerances.
The model also has a reinforcement on the inside and rubber feet made of TPU.
