This is a funnel that screws onto a water bottle.
I use this to pour my silica beads into the water bottle after reconditioning them. It has not been tested with anything liquid.
I printed mine with a resolution of 0.2 for the funnel part and 0.1 for the threaded part with the funnel side down on the bed so there was no way it would get knocked over. Without any supports.
Created in TinkerCAD with threads from the Carpenter Bee Trap.
