Reusable MINI filter cartridges for 3M UNIX MSA JETTA NATO 40mm 3D print model

A set of MINI reusable cartridges i developed during COVID pandemia. Kit includes mounts for Mask Brands:

3M (Jetta Safety) UNIX (MSA Safety) NATO (NATO 40MM, USSR GAS MASKS, 40mm round thread)

Template for material cut is included. Material up to 8mm thikness can be inserted. I recomend carefuly choose material and ita ammount so that you could breath through it.

Printing recomendations: Print with 0.4 nozzle PETG material for maximum strength and reliability. (abs doesnt like threads and can crack when overtightened)

Key benefits:

• Strong structure
• Compact
• Easy to 3D Print (no support needed except Nato mount part)
• Easy to assemble
• Tight fit to masks
• Nice look
• Easy use
• Fast print time
• Pandemia tested
