Portwest® Bayonet To 40MM NATO (RD40x1/7) Adapter
==================================================
This prototype design for a Portwest® bayonet respirator to 40 MM NATO, gas mask thread adapter. This adapter makes the Portwest® bayonet 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:

Alternatively, if you cannot source COTS filters, search thingiverse, there are a number of other DIY filter cartridge designs to mate to other major manufacturer, 3M/MSA/etc. respirator's attachment system.
Part Description:
============
PORTWEST_BAYONET_TO_40MM_NATO_ADAPTER_GEN1.stl
Initial model release.
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:
=========
04/22/2020 - Initial model release. I do not have any Portwest® series 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 Daramcgrath for taking the time to pull the geometry on the filter side and for reporting back that the original proof of concept works on his initial request for MSA® to Portwest® adapter. We hope and pray that this will help keep your front line HCPs in the UK safe and sound.
