Toilet Seat slide-preventer / alignment block (parametric, customizable)

Replacement toilet seat bumpers that include a hook to keep the seat from sliding left or right in case of a "hard landing".

Helps to save the bolts and hinges from loosening or breaking when someone puts high sideways force on the toilet seat.

Note: this design only works on toilet seats with removable feet/bumpers which have two pin holes.
