Dopper Cap Replacement

thingiverse

It's a cap for the dopper bottle, designed to fit perfectly without any issues. The seal works in conjunction with a rubber ring that comes included with the original bottlecap, ensuring it's completely waterproof. Testing has confirmed its effectiveness and I'm currently using it. To further enhance water resistance, consider increasing the infill percentage to a high level and slightly overextruding the plastic by 1-2%.
