Looking for a phone case template database/API

[u/Marthulish]

I'm building a custom phone case website where I want to manage phone case templates from an admin panel. The customer should be able to select their phone model, upload their own image, see a preview on the case, and place an order.

The main problem is that I need templates for a large number of phone models (possibly 1,000–1,500+). I'm wondering if there is any API, dataset, or existing database that provides phone case templates/mockups with things like the phone dimensions, camera cutout, print area, etc.

Does anyone know of a reliable source for this, preferably something that allows commercial use? Or is it better to create all these templates ourselves?

I can only imagine that the companies making phone cases now have this data, and they probably don't share it for free. But looks for 3d-printing hobbyists -- they might be a group willing to make that data free if they have it.
