Hex Dumbbell Boot

Very simple boot to slide onto the end of a hexagonal dumbbell to protect it and the surface you set it down on. Bare-metal dumbbells tend to be a lot cheaper than the ones that have a rubber coating on them. I have tried applying Plasti-Dip to dumbbells in multiple coats to build up a protective layer but it takes a long time and it doesn't work nearly as well as the real rubber coated ones.

These work like the bottle boots I have designed: print them with TPU and press them on. Each dumbbell will need 2 boots. They do take a long time to print, maybe I will make some more optimized ones, this is my first design that I know will work. As currently designed, it has a 2mm wall thickness and has an inside hexagonal opening that is 100 mm between flats. To customize, just measure your dumbbells and use that measurement (in millimeters) to find the scale you need in your slicer. E.g., my 20 lb hex dumbbells are around 102mm from one flat face to another, so set the scale to 102%, and print. You can play with making it tighter or more loose but going straight for the measured size has always worked well work me with bottle boots.
