Sagrotan refill hole screw cover

thingiverse

Yet another screw cap for the NoTouch soap bottles. Designed for a 18mm hole that can be made with a step drill bit. The thread is tapered and the largest diameter is 20mm. It also has an hole in the middle to reduce the amount of filament and print time. I drilled the hole holding the bottle upside down to minimize the amount of chips that are falling inside but I still had to wash it clean at the end. I think that if the plastic chips are getting in the system it might clog or break the pump.
