Coin based Magsafe attachment (Concept)

This is a concept for a strong Magsafe attachment, that doesn't need much other than eight 1 ct coins. The file contains three test models and also the .step files, if you want to implement the attachment directly into your work. The idea is to have a cheap option to connect things to Magsafe accessories like tripods or holders, without the need to buy something (and wait for the order to arrive), while also being standardized and available to a large group of people. Doesn't use magnets, so the attachment relies on Magsafe accessories, that already contain strong magnets. Steel washers might be an alternative for people in countries without magnetic coins (just make sure they're magnetic).
