Designed this simple 20mm portable hangboard that can be attached to a standard pullup bar (32mm diameter) that you can use at home.

Just hook it and hang :D

You'll need to print twice (1 for each hand) or you can clone it and print both at the same time.

Printer Settings:

I used PLA basic with 70% infill (cubic), I've tested up to around 80kg and it held up fine.

I found that the texture was too smooth for my liking and added in the fuzzy skin settings in Bambu Studio; contour, 0.5mm point distance and 0.3mm thickness to give it a bit of texture for better grip.

Do give it a try and let me know how is it :)
