Delta Plus M6000 Jupiter Series To 40MM NATO (RD40x1/7) Adapter
=====================================================
This prototype design for a Delta Plus M6000 Jupiter series respirator to 40 MM NATO, gas mask thread adapter. This adapter makes the Delta Plus M6000 Jupiter series line compatible to RD40x1/7 threaded filter canisters or step down adapters to enable greater cross compatibility of respirators and filters to other manufacturer models.

If you do not have access to 40MM (RD40x1/7) filters, you can use the following adapters to step down to COTS filter cartridges from these companies below:

Part Description:
=============
DELTA_PLUS_M6000_TO_40MM_NATO_ADAPTER_GEN1.stl
Initial model release, M6000 female geometry based on f2knpw’s Delta Plus end cap/adapter.
https://www.thingiverse.com/thing:4297891

Disclaimers/Risks:
=============
1.) Requires 40 mm OD gasket or o-ring on the interior RD40x1/7 pocket to ensure proper seal maintained between cartridge and threads.

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 return to normal users should purchase OEM OSHA/NIOSH/EN standard approved adapters and respirator accessories.

Dev. Notes:
=========
04/24/2020 - Initial model release. I do not have any Delta Plus respirators or filters to check measurements, so please report back in comments for any fitment issues and I’ll release revisions as required.

Thanks to f2knpw for his Delta Plus mask end caps and filter adapters.
