Smartphone stand - flat foldable and portable

I created this smartphone holder in order to have a compact, robust and effective solution that allows me to keep the phone on the desk in an upright position.

It is extremely compact when closed on itself (smaller than a credit card), the dimensions are:

79mm - length
50mm - width
3mm - thickness

Once opened, this holder is able to accommodate any smartphone model, positioned both vertically and horizontally, including heavy and bulky smartphones, such as my iPhone 13 Pro with cover and Wallet.

Thanks to the internal steps it is possible to choose the inclination, in order to make it more comfortable to use the smartphone when it is placed on the support.

I designed this stand to make it robust, stable and at the same time save PLA material :)
