Minimalist 3D Phone Stand Design

I have a rough concept for a clean, minimalist phone stand with magsafe charging meant for smartphones only and to be manufactured in plastic. The idea is sketched on paper, but it now needs to become a fully-defined 3D model that can go straight into prototyping or 3-D printing without extra tweaking.

Once I share the sketch and key dimensions, I’ll rely on you to:
• build a precise CAD model that reflects the minimalist aesthetic,
• check stability and weight balance for typical smartphone sizes,
• deliver print-ready files (STL or STEP) along with a couple of high-quality renderings so I can gauge the final look.
Please include a short note on how you would confirm fit for the average phone thickness and charger cable clearance so I can move to prototype with confidence.
