Honeywell North Respirator to 3M bayonet filter adapter

thingiverse

This is a hack-and-slash remix of AgapeIngenium's very nice adapter models (the 27mm ones). I used Meshlab to simplify the poly counts under 250000 so they'd load in Tinkercad, and Tinkercad to truncate and merge the business ends of each adapter side of the original parts. This remix accomplishes the task with a much lower profile and no internal gasket, at the expense of losing the filter rotation feature. I used some closed-cell antistatic shipping foam as the external gasket on the 3M side, you might choose something better for your application. The text was removed from the adapter sides, but not the top face. There is another remix on the same original part that I feel is a better and better-looking design for most filters than my remix, since it uses less materials with likely similar strength at high infill rates. My remix is 20% shorter and retains the two tabs, in the case the raised detent tabs and a tight mask profile are important attributes for the 3M filters to be employed. Printed in PETG 240c, 25% infill with no supports (hence the stringing on the cone but doesn't affect usage at all).
