Medtronic pump battery change coin

I designed a small coin to open the battery compartment on Medtronic pumps. I always get the battery change notification when I don't have any coins to open it.

I added the Loop logo and a hole to carry it with your Rileylink.

Issuing a filament change on layer 10 will let you use a different color on the Loop logo. This can be useful in households with more than one Rileylink as a way to tell them apart.
