Bunn Pump Pot Toggle

https://www.thingiverse.com/thing:2988237 is a newer and beefier model that will work better and last longer.

Bunn Pump Pot Toggle. Bunn makes a pump pot to keep coffee warm. After heavy use, a plastic toggle inside the lid weakens or breaks. Bunn will not sell a replacement part. I've printed this with PLA on my printer and it is currently working with heavy use. This design has a little bit thicker area where the weak spot is. Only time will tell if it is able to work for years.
