Custom Filter for GOST 8762-75

thingiverse

I printed a revised version of this filter, which is designed to address problems I encountered previously and will be tested tomorrow. The picture shown here is from the previous iteration. Filter A features the standard GOST 8762-75 thread design. Filter B boasts a distinctive large rim adjacent to the smaller threads. Notes: The lid has been intentionally made larger than the casing in order to facilitate easy opening. New prints may be somewhat too tight, but after repeated use, they will loosen. I advise partially screwing it in and then turning it back and forth until it turns smoothly before tightening further and repeating this process until it turns easily. The mask design can be found at https://www.thingiverse.com/thing:4268612 (use Filter B with that). Thread files are available at https://www.thingiverse.com/thing:4260984.
