Overhead shower gel screw cap

thingiverse

Recently my upside-down shower gel cap disintegrated and I decided to create a new one. The original cap was made of cheap material and lacked a silicone valve. My initial attempts to simply print a new cap with a thin bottom and a cross-cut inside the bottom failed, as the gel continued to drip endlessly. To resolve this issue, I developed a threaded upside-down shower gel cap with a valve from any upside-down kitchen bottle, such as a honey or BBQ sauce bottle. I used an empty BBQ sauce bottle and cut out the valve to fit into part 1. Instructions: Cut out the valve from any upside-down plastic bottle to fit into part 1. Adjust the inner diameter or thread winding in OpenSCAD (or leave it at 27 mm). Then print both parts. Knead a chewing gum or other sealing material into a ring slightly larger than the open hole and place it inside part 1. Press the new valve through the ring from the inside of part 1. If it doesn't fit well, use a hair dryer to weaken and widen the hole. Knead another small sealant ring and place it around the valve. Press part 2 onto the valve. Again, if it doesn't fit into part 1, use a hair dryer to weaken it. The hair dryer also helps when screwing the cap onto the shower bottle for the first time.
