Hello, I am threejs expert and I can absolutely do your project. I can show you my work demos right now. I worked on 3d modeling, 3d model viewer.
I also have done object slicing proejct recently.
I am currently working on 3d machine automation system.
I think I can do your project using Aframe which is to implement AR and VR.
Please contact me and discuss your project if you are interested.
Thank you.
I am waiting...
