When I want to quickly go out to get a coffee or slushie at my local stores, I only need my phone and house key. Normally I would be carrying my phone, wallet and keys which gets surprisingly bulky with everything together. I have a spare house key I take with me for these trips but its pretty insecure. 

So to solve this first world problem I designed this minimalist key holder that utilizes the magsafe features of the iPhone and other similar adaptions!

The print file is pretty basic but worked well for me, my P1S has the default 0.4 nozzle and used 0.2 in Bambu Studio, so pushing it to 0.16 should still give good results.

The magnets I used and should fit are 5mmx2mm which I purchased from Amazon:

When assembling, double check the orientation of the magnets matches up correctly with the magsafe ring of your device. Pop your key in and then insert the lock piece to hold secure. When wanting to remove the key, you can rotate the lock to give you move leverage to pull it out.

I've uploaded 2 version of the case, for Right and Left hands as well as a lock variant that allows up to 2 keys (the small guard will not protect the upper key from rotating). 

For testing I used some blank key templates I made, try these out if they are similar to your keys or if you want to design your own key accessories:
