There is no quick explanation that could be quickly compacted into a forum reply. There are several methods you can use such as Raycasting, Wireframe, Tri-fill, 2.5d (top down 3d effect created when layering multiple stamps on top of each other) and more. You could probably quickly search up any of these on scratch or YouTube for a tutorial. Be warned though, Scratch was not made for 3d and may cause major lag as well as creating major difficulty in the creation of games using these methods.

I could probably explain the concept behind some 3d engines if you want.

use these playlists to help you start creating 3d:

You can't upload .html Python projects to Scratch, so that's the first thing you must know. You can only upload .sb3 projects (the project extension used by Scratch 3.0).

Second, there are a lot of methods using pen projects, and a video by griffpatch himself, so check it out. I hope this helps.
