Rep QuickDraw Bracket

I love my Rep Quickdraw dumbbells but there are no screw holes to mount the cradle to a stand. I built a stand out of wood and wanted to mount the cradle so when I lift them out the cradle stays put. MUST BE PRINTED IN TPU. It is an “imperfect” design due to the oblong shape of the cradle and the fact that my design skills suck. But the TPU allows the bracket to stretch around the roundish shape of the cradle and lock in place with some basic wood screws. Top and bottom are 2 separate pieces.
