This is one of around 20+ models I have recently designed for compact push up bars.

I am publishing this design because it is sturdy, printable on a small printbed (Prusa Mini) with minimal supports and very compact. 

I have uploaded versions with or without magnets (diameter 10mm, depth 5 mm), which can be easily glued in place for easy carrying. 

I print with a 0.4mm nozzle and 6 layer perimeters and 15% gyroid infill with enough strength to carry me (approx 80 KG). 

Enjoy!
