In the process of building kit for LARP/Halloween I decided I wanted a dual tube system going form the PAPR to the TAPR, I tried using T splitters with standard 40MM NATO threads on it but the tubes would get tangled up and hard to work with. I wanted something that I could easily just snap on and off but sturdy enoudh to stay put during use. So I designed these fittings, there is a male and female screw on fitting; they have a corresponding piece that slides into the other with a small ring that fits into the groove keeping them together.
There are also two T-Splitters, one with two male and one female; one which is reversed. Included are the Bambu 3MF files for them already set up in an optimal printing position.
NOTE: This is intended for Cosplay/LARP and is not meant to be used in an actual situation requiring the use of a respirator/gas mask. If you find yourself in that situation, please use only approved connectors and tubes from the manufacturer.
