DIN FISH: Mares MR12 DIN Ring tool
thingiverse
Tired of scraping the skin of your hands off after a dive to undo the DIN ring of your Mares Regulator? Search the internet no more, here comes the DIN FISH! The DIN FISH permanently attaches to the knurled ring of your first stage Mares regulator and can be used to easily remove it from the tank without peeling the skin off from your poor soggy hands! (hopefully... Not tested yet... :-) For the DIN FISH you need roughly 25g of plastic and any 3D printer, a M5x16mm hex socket head screw and a M5 dome nut (any nut will do, I think the dome is neater). I recommend stainless steel.
