Friction fit will hold tight during transport and riding if using to protect secondary battery. Just feed the unit through the loop to connect it to your bike. Also, works great for dual battery bikes when the second battery isn't required.

Nice 3D printer project! It's about time a cover was designed specifically to protect these contacts.

A few years ago, I bought 40 of these for a project I was working on.

It turns out, they are a perfect fit for the Hailong 4 and 5 blade connectors.

They aren't red and weren't specifically designed for this purpose, but they've worked fine for me. I still have 20 or so left and I'm willing to send a couple to anyone interested for the cost of postage.
