Dumbbell bar

After losing one of my dumbbell bars during a move, I figured I could probably print one on my 3D printer. The bar was tested with a total weight of 20 kg and is sturdy.The key requirement is that the bar itself is printed with 100% infill.For maximum stability, the bar should be printed horizontally with supports.The nuts can be printed with 15% infill.I tested both using eSUN default PLA. The threads are dimensioned so that they still function even with slightly rough overhangs.
