This is a total remake of my original versions. This time I made them in FreeCAD using a spreadsheet to control all aspects of the design for an easy and quick way to make changes.

A few years ago the area around my residents bloomed with all sorts
of mushrooms, then again in 2021.

Powered, Air-Purifying Respirator (PAPR) and More.

I have been working on these designs a few years ago and have plans for commercial plastic injection molded add-ons / that enable disposable and face respirators to be airtight. They require a scuba mouthpiece and nose clips.

Once installed ALL air goes through scuba mouthpiece and through air filters, NO leakage from side of masks or for people with beards (like myself and why I created these, so I do not have to shave my beard).

Due to COVID-19 I’m posting my 3D prototypes for personal use. With hopes of finding support and funds that I have no way to get myself.

I have been working on several different types of additive and subtractive systems. SO far only making them to the CAD designs.

Due to current world issues I’m just posting them to share.I would love to find funding to get these designs built and tested.

Here are some older images I took of various 3D prints. For the most part, it was the failures that look cool.
