My replacement hinge design for when your hinge pin snaps on the toilet seat. Suitable for china bowl types only i think.
Split object into 4 items. duplicate collar and pin so you have 2 pins and 2 collars. Orientate the pins and collars standing upright. The LH and RH bodies stay orientated as is. Print at 0.2mm layer heights in PETG. You will need two M3 x35mm long stainless button head bolts to fix the pins to the bodies. Push the collars firmly into the base of each body. (superglue optional). All done. Bolt it together and it should last a lifetime.
