SCUBA drysuit glove system (a simple low profile ring)

thingiverse

My glove system which I use for cold water diving to keep my fingers dry and warm. After destroying several commercial drysuit gloves I decided that I can go cheaper with my own idea. I also wanted it to be as small as possible, for freedom of movement and adjusted to the shape of a (my) wrist, which is rather oval and not a circle in the cross section (that is the case for every human). You need a drysuit with intact wrist seals (latex). You can use commercial drysuit gloves with a wrist seal attached (as in the picture) or what I prefer now, chemical industry heavy duty rubber gloves (they come cheap). See comment for more info.
