comic book stand 3d model

I would like to create a 3D printed comic book scanning stand that I can scan comic books with consistent accuracy with no shadowing. I want the stand to be snug with easy drop in and removal access to the base where the comic will sit for the scanning process. It must fit bagged cardboard backed comic books for quick snapshot and entry into an app. Want the stand to be height, forward adjustable and sturdy with the stands being able to snap onto the base for easy removal and storage. The phone cradle must be solid and able to keep the phone from moving for constant scansfor the iPhone 14 Pro Max + OtterBox Defender Cradle. I would also like the base to be expandable later to be able to make attachments for magazines, books and a drop in tray for cards something like a drop in frame for the books and magazines and a drop in frame with card sized open ended drop in box for the cards
