I have managed to redesign and print fully functional seat knob with lid for oldschool BRIDE seats, they tend to break and wear over time so it's nice to have new replacement. Lid is attached to knob/dial by 5x2mm neodymium magnets, which have to be glued onto the lid itself and the knob (so you need 4 magnets). Knob is secured onto seat adjusting mechanism by a small clip which can be sourced from local shop with bolts/nuts etc. Added ironing to increase smoothness of top surfaces, which needs to be adjusted to your filament/printer.
