Ikea Skadis Holder for your Apple Magsafe waller or powerbank.
The model requires neodymium magnet to be glued inside.
I used these (https://aliexpi.com/KZQ5) with adhesive tape already installed
Feel free to remix with maybe more stable skadis mounts, I have tried experimenting with nut inserts and screws. Another idea could be to remix it so the magnets are inserted during a print and enclosed. I have not had any problems with the adhesion yet. And the wallet or powerbank hold pretty well.
