CR2450 to CR2477 adapter

I've been dealing with two types of SmartThings sensors, some that require CR2450 batteries and others that call for CR2477 batteries, and it was getting annoying having to stock both. Changing the batteries in devices using '77 batteries more frequently doesn't bother me at all, so I came up with a solution - an adapter that allows me to use CR2450 batteries in holders meant for CR2477 batteries.
