Bottle and Screw Cap 46

thingiverse

Here's the rewritten text: Bottles need screw caps to seal properly. Screw caps protect the bottle from contamination and ensure a secure closure. To remove a screw cap, hold the bottle firmly with one hand and turn the cap counterclockwise until it comes off. The threads on the bottle are important for ensuring a tight fit between the cap and the neck of the bottle. In this 3D model tutorial, we'll be working with a bottle that has a threaded opening designed to accept a screw cap.
