Toilet Flapper Wrench for 8 sided nut

prusaprinters

I was fixing toilets in my house and found Peterthinks' wrench design for the big hex nut on 2 inch flush valves.   It worked great, but I also had a need for an 8-sided nut wrench as well to mount the new valve.  I took inspiration from his design to create a companion wrench.This is also for a 2 inch flush valve, but the distance between the flats work with 76-77mm (approx. 3-inch) 8-sided nuts.
