I don’t have a 3d printer to be able to design and print a mold so I have to build up the epoxy over multiple pours. The first pour is already on in the photo but it is hard to see with it being almost crystal clear. Couldn’t get the damn air bubbles out from the area between the pins and the plastic without risking burning the plastic with my torch.
I am not adding any sort of loop on purpose, but will be adding enough of a little grip area to be able to pull it out. As is I can pull it out but with no good grip yet it is hard. The magnet is hopefully my small form solution to making it harder to loose when unplugged and not for attaching a loop if that makes things clearer. If I did want a loop then I just need to drill a hole in the epoxy that will extend past all the metal though, so, no, the magnet won’t be in the way.
Also I 100% fucked up the polarity on the magnets and now need to redo the magnet inside the remote case. I knew it could be an issue and yet did nothing to prevent it 
It is called planning ahead. I know there is a good chance I’ll end up loosing the loopkey when out and in a store, so I’m designing it to prevent that by adding magnets to things I already have to carry with me. The remote, probably will add one to the inside of the enclosure somewhere, and I’ll add one to my key ring. Giving me at least 3 easy places to quickly attach it to for safe keeping. If it takes to long to secure it I know I won’t use the method most of the time hence the magnet.
but also I keep my keys small and light as well and a clip would be too bulky. The small ones that do exist are too hard on my hands to open.
There are a lot of things on my boards where I could have taken a faster method, but didn’t because I don’t like how it would look or I wanted some cool feature I thought of.
