Your toilet seat stays solid and secure with this 3D-printed bolt and nut set. No more wiggles. No more tightening every few weeks. You print this set on demand, customize it to fit your toilet, and install hardware that actually stays put.

The design uses a 3/8 inch by 2 inch bolt with specially tight threads so loosening becomes nearly impossible. The set prints as one complete assembly plus individual parts for easy access. Print the bolt with 2.5mm walls and triangle infill for maximum strength. If the washer sits too tall on your seat, simply scale the height down by 50 percent to fit perfectly.

Made from the US, designed by Random_Al. Thread the nut backwards first to activate the tight grip, then watch it work reliably for as long as you own your toilet.
