We ordered a "FEIERDUN Adjustable Dumbbell Set on Amazon for one of the kid's birthdays, and the plastic nuts that came with it did not match the square threads of the bars.Instead, their fitment was loose, and the threads were so thin that I knew they would strip quite quickly.This upgraded model meshes quite a lot better with the square threads on the bars, and is a fair bit tighter, giving me more peace of mind when the kids use the set.No supports required, and can likely be made from PLA, I just made mine from PETG as it was what I had available and would likely hold up a bit better over time. This is a link to the specific set these fit:https://www.amazon.ca/FEIERDUN-Adjustable-Dumbbells-Connector-Kettlebells/dp/B0C2TDDTYX/ If you find that these fit another set, too, let me know and I will update this description.
