40MM NATO to Honeywell/Honeywell North® Adapter
=======================================================
This prototype design for a 40 MM NATO, gas mask thread, to Honeywell/Honeywell North® threaded adapter. The adapter should make RD40x1/7 threaded full face CBRN masks compatible with Honeywell/Honeywell North® threaded chemical, combination, and particle cartridges.
Part Description:
=============
40MM_TO_HONEYWELL_NORTH_ADAPTER_MONO.stl
Gen 1 (M27x1.5), one piece construction adapter, for Honeywell/Honeywell North® threaded filters that do not require clocking.
40MM_TO_ HONEYWELL_NORTH_ADAPTER_INNER_SHELL_LOW.stl
40MM_TO_ HONEYWELL_NORTH_ADAPTER _OUTER_SHELL_LOW.stl
Gen 1 (M27x1.5). two piece construction, not for clocking purposes, but to be also backwards compatibility to outer shell from previous Gen 4 40 MM to 3M™ bayonet adapter if already printed. Tolerance are more forgiving, lower, to enable ease of 3D printer variation.
40MM_TO_ HONEYWELL_NORTH_ADAPTER _ADAPTER_INNER_SHELL_HIGH.stl
40MM_TO_ HONEYWELL_NORTH_ADAPTER _ADAPTER_OUTER_SHELL_HIGH.stl
Gen 1 (M27x1.5), two piece construction, not for clocking purposes, but to be also allow backwards compatibility to previous outer shell of Gen 3 40 MM to 3M™ bayonet adapter. Higher tolerance parts requiring proper scaling and calibrated 3D printer.
40MM_TO_HONEYWELL_NORTH_ADAPTER_MONO_GEN2.stl
Gen 2 (Revised Threads ~M26x1.57), one piece construction adapter, for Honeywell/Honeywell North® threaded filters that do not require clocking.
40MM_TO_ HONEYWELL_NORTH_ADAPTER_INNER_SHELL_LOW_GEN2.stl
Gen 2 (Revised Threads ~M26x1.57), two piece construction, not for clocking purposes, but to be also backwards compatibility to outer shell from previous Gen 4 40 MM to 3M™ bayonet adapter if already printed. Tolerance are more forgiving, lower, to enable ease of 3D printer variation. Outer shell did not change, so did not update.
40MM_TO_ HONEYWELL_NORTH_ADAPTER _ADAPTER_INNER_SHELL_HIGH_GEN2.stl
Gen 2 (Revised Threads ~M26x1.57). two piece construction, not for clocking purposes, but to be also allow backwards compatibility to previous outer shell of Gen 3 40 MM to 3M™ bayonet adapter. Higher tolerance parts requiring proper scaling and calibrated 3D printer. Outer shell did not change, so did not update.

Disclaimers/Risks:
==============
1.) It would appear Honeywell/Honeywell North® filters have gasket on the filter side, but check to ensure gasket/o-rings properly sealed between cartridge and threads. Source a gasket or O-ring with a 27 mm OD [Gen 1] or 26.016 mm OD or 1" OD [Gen 2].
2.) 3D printing materials are not resistant to many solvents, are water soluble, and degrade when exposed to chemicals. 3D printing this adapter is only a temporarily ad-hoc solution against biological threats. Once supply chain returns to normal, users should purchase OEM OSHA/NIOSH/EN standard approved adapters and respirator accessories.
Dev. Notes:
=========
04/07/2020 - Initial model release. In work, pending support and feedback from 3D printing community for any fitment and model revisions. This is a proof of concept as I do not have either Honeywell/Honeywell North ® respirator or filters to check and ensure fitment.[Gen 1 - M27x1.5 Thread for Honeywell/Honeywelll North ® respirators, As Reported By Clownrock95]
https://www.thingiverse.com/thing:4252141/files
04/08/2020 - Revised model, due to 3D printing community feedback on fitment issues with threads, see comments. Unknown if Honeywell/Honeywell North ® respirators have legacy and newer threads to explain discrepancy, or if chasing 3D printing tolerances. But updated threads to match erniepike's Honeywell/Honeywelll North ® adapters. [Gen 2 - Updated w/ erniepike's Revised Threads]

04/14/2020 - Updated with engraved markings to differentiate between adapters.
