This is an adjustable phone stand that works with your phone in the vertical or horizontal position. Its intended purpose isnt for charging phones but mostly for watching videos etc therefore there isnt a hole for charging. Designed around an iPhone 7plus but should work with any other phone. Let me know if the legs need to be made longer for heavier/larger phones. If that's the case, only the base needs to be reprinted. I'd recommend sanding the interface between the base and stand so its smooth, the track shouldn't need to be sanded but that might change between printers etc. This is designed to be a tight fit so that the stand won't change angles unless you adjust it yourself. It has a 35° range of motion from 90°-55° which seems to be good for most uses.
Supports are only necessary for the Stand and not the Base.
