Ability to upload .stl files in forms

Hello, for a start up I’m working on I need people to be able to upload .stl/CAD-files (up to 20MB). Since this isn’t possible with Webflow’s built-in tools and I can’t code I’m looking for a third party solution. Preferrably under €15 a month. It would be great if the uploaded file automatically gets uploaded to a cloud storage.

If a certain API can also fix this, could you please explain how to set it up?/link to a tutorial?

In the University there is a section related to third-party tools with info and links to the providers. Take a look there to see if you can find what you need.
