Push Up Bars / Parallettes with Thick 40mm Handles

These push up blocks are designed to be very comfortable on the hands, with handles being 40mm in diameter, which happens to be the handle diameter of my favorite kettlebell. I designed these to be printed in optimal orientation with no supports. The handles have a flat spot on the bottom side, to be printed horizontally.

I used epoxy glue to hold the parts together.  I wrapped some tennis racket tape around them, to increase the comfort some more.

Printing

Print all parts horizontally (both handles and the base pieces). Increase wall loops (perimeters) to 4 or 5 to add strength. Infill does not matter that much for strength. I used 40% Cubic. I printed my bars in PLA, and been using them for a few months, and they are holding me just fine (I weigh 90kg). But I'm only doing push-ups, so they are holding about quarter my weight each.

I also enabled "Insert solid layers" in Orca Slicer, to print a solid layer for every 5 mm of height, to add even more strength (see screenshot below).

The rubber feet I printed in TPU, but if you don't have TPU, just cut out some rubber rectangles instead.

Obviously, you need 2 handles, 4 bases, and 8 rubber feet, for a set of 2 bars.
