25 April 2020 edit: For those considerng this, hang on. I am reworking it to fit a larger diameter PVC pipe, while remaining in a small printer volume. The 40mm may be too narrow.
Thanks for taking a look.These are components for the assembly of an extra oral aerosol removal device. The device can be made using all the components in this collection. The rest is made up of off the shelf hardware items freely available. The suction is generated by a vacuum pump, sourced by yourself. At time of publishing the components were tested for fit and accuracy, but because of lock down restrictions a full assembly could not be made to test. The designer expect to make improvements, as this will probably be a beta testing type approach. Included is a relatively detailed pdf for what you need to do, and how to go about it. It should not be hard to assemble, but the services of a plumber is a good idea. Hoping this could be an answer to the problem of aerosols
