These are replacement handgrips modeled for the Iron Gym door frame pull up bar, but should work for any bar with the same diameter (Bar ID 25mm), or you can probably scale them to fit any bar with other diameters.
These are designed to be printed in TPU so they offer comfort and grip, I have the print settings to use 3d honeycomb infill which gives them uniform flex to conform with your hands.
I also modeled replacement contact pads for this pull up bar, if you want to download those you can find it here: https://www.printables.com/model/1182372-pull-up-bar-replacement-door-frame-contact-pad
