My toilet lever broke and I didn't want to buy a new one. This model is certainly not overengineered and the tolerances are pretty tight in most places but if you'd rather print one than order one for whatever reason (or just need a temporary stand in) this should hopefully do the job.

update: after a few months it snapped and I made a reinforced version of the part that snapped and I've uploaded it.
