Coffee Can Style Russian GP-4y Gas Mask Filter

thingiverse

This is a replica of the GP-4y Russian gas mask filter that was manufactured during the 1960s and 1970s. It features a coffee can style design, which gives it its distinctive appearance. For optimal printing results, I recommend orienting the model on its side, allowing it to print with minimal supports required. FEATURES: * Compatible with GOST 40mm thread * Bottom hole is identical in size to most bottom plugs for 40mm filters, making it suitable for use with rubber stoppers from old GOST filters or generic NATO plugs. * The design incorporates a threaded connection taken from the Russian GOST filter model on Thingiverse, while the rest of the design was created by me. Note: This is not an operational gas mask filter and should not be used as one.
