this is something my company of makers is about to start mass producing anyone can message me for the vacume form blocks please use this design as much as you would like.
this design allows you to re use and sterize, clean a single mask instead of throwing away one every time. you can just take the sheets of filter out and pop some new ones in. the jagged part of the snap ring at the bottom is so that you can push on it and increase the diamter of the filter cover bit releasing it we will be able to crank these out by the thousand stack a sheet of thirty on top of eachother and water jet out about 120 in a pass.
