I'm doing exactly this for my mum at the moment. Trialing various apps and methods. Best so far has been polycam (tho only with photos, hers is an older iphone) uploaded to sketchfab for embed .. that said I think we're content with not shooting the bottom of the various pieces, so they are presented on a table or a wheel. Good luck!

Thanks - Ill have a go with that!

Well what I usually use is Meshroom, where you simply add your photos and let it reconstruct the object. I haven't had particularly good results with it (likely due to my photography "skills"), but it was good enough for what I needed. You could check out a guide for that since it should be easiest to start with.

I tried meshroom originally, but it was amazingly slow compared to some of the commercial offerings. Searching, I see there is some hidden flag for GPU, so ill see if that helps.

In the past I did exactly this, creating 3d models of ceramics made by my partner, with my Xperia xz2 phone. It had some built-in app for this. Though I have nothing to compare it to, the results where quite good, even used it to 3d print copies.

This is something that QuickTime VR did reasonably well many decades ago. So consider using a turntable and capturing a short video clip.

I purchased a Pivo to do exactly this. The problem is more with the fixed angle you cant always capture enough of both the inside of a bowl and the outside. But maybe i can use this to assist with capture....
