Aron

This is a model of the Aron based on the dimensions from Parshas Terumah. I used Silk Gold PLA for the outer and inner boxes, and "Wood" PLA for the middle box. I purposely made the Keruvim a little geometric and less realistic looking because I wasn't sure if too realistic would be ok from a halachic perspective.
The boxes are not so thick, so unfortunately I don't think it would be able to be scaled down all that much.
Enjoy! I'd love to hear if it ends up being used in a classroom setting!

(Only the Kappores needed supports)

Note: When I got a SOLIDWORKS license I redesigned the Kappores. One of the pictures show the new vs old Kappores
