Print this sitting flat on the U part with the snorkel attachment pointing up. There is a double male - 3M bayonet to connect the adapter to a 3M Filter. I will soon upload a bayonet holder for generic round particulate filters. The double-male connector and the filter base parts will need a plumbing washer to create a seal. Alternatives are silicon sealant or hard-glueing them in. I have uploaded a 'tube only' version for remixes, and a 'straight to 3M filters' version of the t-bar. Yellow filter is RP461/RP462 which is for dust only. (The obelisk thingy is to block the center 'exhalation' channel in the mask.) update: bayonet version reuploaded with the end-caps merged harder^2 update: single filter bayonet version update: added simplified dust filter canister base - so you only print that and the filter-cap. Excellent remix here - https://www.thingiverse.com/thing:4246316 - might better suit your needs, this remix includes a ventilator connection.
