Desktop stand for Magnehelic differential pressure gauge

A desktop stand for a Dwyer Instruments Magnehelic differential pressure gauge. These are great to tune a second stage scuba regulator and they can be had very cheap on eBay (Kleinanzeigen) and the likes.

The stand turned out to be a bit monstrous, but it works great and looks good. A print volume of about 250mm is needed in one direction. If there's demand i can try and create a smaller one.

The only problem is that the Magnehelic is so ancient that it only uses insane imperial units for it's interfaces and dimensions, which makes getting the hose fittings, plugs and screws almost impossible. Turns out a G1/8" BSP thread is of course not the same as a 1/8" NPT thread.

I found the hose fittings and plugs on Aliexpress in the end and the screws on Amazon(.de).
