thingiverse

This is a wrench key for the 3m mask filer opening. This key supports with various printed filter cartridge for viruses, such as follows: 1. 35mm Filter capsule for 3M 6200 6500 (size S) - ALPHA 2. 龍捲風 Filter capsule for 3M 6200 Gas Mask (fit38mm filter) - Ver.7.3 by ALPHA 3. V3 3M 6200 use surgical mask as filter adapter From my experience, it is hard to open/close the filter by hand, even I print these out with right dimensions. So, I seek a simple key which is easy to print and use. The original key is easy to use, but very time-consuming printing progress. Therefore, I created this key to help Hong Konger and others from foreign country fight against Novel Coronavirus Epidemic (officially named: CODIV-19). By reducing the printing materials and time, which is a great one for mass production. Of course, it is durable for long run.
