This is another shell for making your own DIY Dumbbells with concrete! And this one holds more concrete! Just print, and fill with cheap concrete (optionally insert 1/2" rebar through handle for more strength) and let it dry and you have a nice, effective dumbbell for WAY less than the store bought ones. Can be scaled up or down for more/less weight!

At 100% scale it just fits an Ender3 style printer, coming in at 242mm.

Designed to print with no supports, on end with the filling hole at the top.
