The battery clamps pictured above are often really difficult to clip onto your mc battery. And to access you're battery in the adv-field you've got to remove part of your luggage, remove your seat, remove the battery cover... you get the picture. To speed things up, I (and a few others I'm aware of) have purchased these EC5 battery harness leads pictured below for permanent installation on your bike/s.

Unfortunately those harnesses do not come with a cap of any kind. In time, I figure the metal contacts will eventually suffer some corrosion. My ADD nature with bike setup forces me to wrap and tape a piece of plastic to cover the connector to hopefully prevent corrosion. However I figure 'someone' out there must make a cap. Plenty of googling later... no luck finding a cap. But I have found someone who has uploaded a 3D printer file for a cap that he designed - pictured below. I've downloaded it - it's an "stl" file.
I know nothing about 3D printing. Is an 'stl' file generic for all 3D printing? Would making up a small batch of caps (say, 10 or 20?) be relatively straight forward without being too expensivet? And if the answers are positive - does someone in this club know anyone who has access to a 3D printer?
Are there any others here interested in buying a cap or two?
(PS - post up "PM sent" here if sending me a PM. For some reason email notifications of incoming PM's seems to be hit and miss for me.)
