Kubi dry glove system ring size tester

I have struggled to determine the correct size for Kubi dry glove connectors, so I created these rings to help me choose the right size.

Kubi manufactures dry glove systems that allow users to connect gloves to a dry suit used for scuba diving and other water activities. When purchasing a Kubi dry glove system, you'll need to decide on the size of the aluminium connector ring.

These test rings are intended to help you easily choose the best size, ensuring a comfortable fit without any unnecessary bulk. The model comprises four rings with varying inner diameters from 70-100mm. The diameter is noted on each ring.

Print the model and choose the smallest diameter your hand still fits through.

Note:
I am sharing the model in case it is useful for others; however, I take no responsibility should anyone buy the wrong connector size based on these test rings. Try the real thing in a dive shop beforehand if that is an option.
