Screw-Top Container

thingiverse

I designed this container as a test to gauge how hard it is to produce threaded components that mesh together seamlessly. The main challenge lies in achieving the perfect balance of clearance between the male and female threads. Fortunately, I only needed two attempts to hit the mark. It's worth noting that these two parts feature left-handed threads, which are essentially the opposite of standard threading. To attach the top part, you turn it counterclockwise, while removing it requires a clockwise motion. When printing complex designs like this, it helps to start with a series of partial on-off movements to smooth out any minor bumps caused by the printing process. Given the tight fit between the threads, be careful not to over-tighten the top part, as this might prevent you from removing it later.
