Fluke 189 II / 287 / 289 Jack Plug

I have this irrational fear that when i'm handling IPA, resin, CA, silicone, hotglue, water and other liquids on my desk, i'll mess up and pour it inside my multimeter's unused probe jacks.

It's completely irrational, especially considering i normally keep the multimeter propped up.

So i've decided to design some plugs, just for my own ease of mind. The idea is to keep probes plugged into two of the jacks, and plug up the unused two. The reason description and tags mention specific models is because these specific plugs have been designed to NOT trigger the Fluke's probe detection (there are IR LEDs and photodiodes inside the jacks that detect when you plug a connector in - which enables it to pop up a warning if you've got the leads plugged wrong for the chosen mode).

Also, the tolerances are obviously pretty tight - plugs have been designed so they don't fall out, but aren't too hard to plug in either, however depending on your particular printer and material, YMMV. If you're having issues, try scaling them up / down a little.
