About this 3D model

So this is very simple and easy to use, I got prepare 2 version 3mm and 4mm thickness. Both side have 80mm slot to let you put in your lithophane photo. Hope you guys like it and please if you have something to suggest, contact me. Updated for the 18 Dec Now you can download the free version that don't have my e-mail mark on it. And the STL is more smaller size! Thanks!
