Watertight Screw Cap Container

Given that most screw caps for bottle and containers are made from polypropylene (in an injection moulding process), we thought we'd see if we could 3D print a screw-cap container using our modified-PP filament. Thanks to Thingiverse, a design already existed (designed by nophead www.thingiverse.com/thing:84). So we printed it with F43 TOUGH filament, using 0.3mm layer height and 100% infill.

Not only did it print well, the container ended up being watertight! Here's a short clip for demonstration:
