carabiner keychain mobile phone holder

23.3.2025

update, added model v2_13mm_75°. improves stability of 13mm version for phones in vertical position. Phone is more upright and does not tip over if you put a phone with a width of e.g. 11.5mm in the holder

Keychain Phone Stand

Created as a minimalist design, and easy to use as a keychain.

In horizontal position, just use one holder.

Using two holders in horizontal and vertical positions, the phone is stable. In the vertical position, you need to choose the correct holder size, 11mm or 13mm, otherwise the center of gravity is placed backwards and the phone may tip over.

Tested and photographed with a Samsung A55 phone in a transparent case in the 11mm version, I added a 13mm version for a larger case, in most cases the 11mm version will be sufficient. With the 13mm version, there may be a case where the center of gravity in the vertical position shifts too far back and the phone falls over, this is a compromise for the small dimensions of the keychain.
