Water bladder drying ball

Print a couple of these balls to hold your water bladder open to dry. My water bladder doesn't have an easy way to hang it to dry. I've tried laying it out with various whisks and spoons to prop it open, but it was never good enough. Now I'm printing a solution. Use this after cleaning your water bladder to keep it open and drying. 3 walls, 12% cubic infill, supports required. Each ball and its supports requires about 30 grams of filament. I used Elegoo PLA Plus. To customize the dimensions, scale it in your slicer or copy & edit the Onshape CAD document. Note: 3D printed objects are not considered food safe.
