Phone holder for wallets

This is the thinnest 3d printed phone holder (maybe). It's as thin as two normal credit cards and it'a also conveniently sized as a credit card to make it fit inside most of the wallets, in a credit card pocket or on your phone wallet.
It features a super thin hinge (it's just 1.6mm in diameter) that makes it unexpectedly functional. There's a one slit and a two slit version with a second steeper angle if you prefer to use your phone nearly vertical.

Features

• Super thin: just 1.6mm folded, or two credit card thick, so you can put it in your wallet and never forget it.
• Unexpectedly stable. You can use your phone without worrying of tipping it over since the three point support is very stable (the second, steeper angle is less stable and meant for mostly watching).
• Double face decoration: one side is flat and has your plate's texture, the upper side has a light decoration thanks to the exposed inside fill texture, so you can use it with one side out or flip it.
• Quick and easy print. It takes just around 15 minutes to print and uses very little filament.
• Good to test printer precision. The hinge is very small and needs a well caibrated machine and filament.

Tips

Be gentle with the first folding of the card, possibly fold it while it's still half attached to the printing bed to exert uniform pressure along the hinge line. The hinge doesn't go beyond around 290°, do not force it.
If the hinges come off the housing, they can be repositioned by applying a little pressure.
I've tested with 3 pla filaments (bambulab and polymaker) and a petg without issues, with some filamnets the hinge is a bit harder.
