I wanted a travel phone stand that folds, a packable design. The card style ones would always break for me. This is far more durable. It has a detent that holds the support arm in place when deployed for phone holding. This is a print in place phone holder, no supports required. Extremely simple, yet functional design. I do recommend printing in .16 High Quality Bambu profile for best results. Easy to store in a vehicle or use in a vehicle on the dash or center council.
