3D Printing Forum

Hi! I am build a touch screen terminal for a 3D printing studio. I've been looking at sites to find free 3D models
found three:

https://www.yeggi.com/
https://trofp.com/
https://www.stlfinder.com/

on the first and third meet paid models, recommend more similar sites please

P.S. I know about thingiverse, but it has an awkward search mechanism

I use this one to get 3D cad files:
