Vacuum Release valve
Description
This is a vacuum release valve for a shopvac add on 5 gallon bucket. Too much suction collapses the bucket. 5/16 x 3" bolt or smaller diameter found at hardware store. any spring of your choice See picture on how to assemble. You can use duck tape or any type of sealant for a gasket (flex seal?) between the body and the stopvalve. The idea was how quality cheap can you make it functional. I glued the bolt hex head into the stop valve cap or you can fuse the bolt in the cap by using a soldering iron and extra filament.. Using the spring spacer depends on how large and tall your spring is. Print at 20%
