My first foray into 3D design. Done on iPad Pro, using Shapr3D.

As requested/suggested (thanks tollbringer), the box dimensions are 160mm x 80mm x 40mm.

I will look at revising the lid, as I am not 100% sure the lid inner edge is quite right.

I will be looking to improve on and expand my design collection. Just let me learn how to design first :-)
