I needed some paralettes (Push Up Stand/Bar) to reduce the stress on my wrists doing push ups. I had some 2,5 cm diameter dumbbell rod in my room. So I designed a stand to use them. I printed the main part with the standard profile (15% infill), which resulted in good stability, but feel free to use more infill if you want to get even higher stability. The non slip part is printed in TPU and 75% infill.
