X-Frame customizable

###This is a simple, customizable, wallmounted fotoframe.

@Pixelrichie made a simple but nice photoframe that didn't fit my photosizes. I redesigned it with variable width and height. The thing found here is for 13x18 cm pictures. Copy my onshape model [here](https://cad.onshape.com/documents/0460c1030e9859828005ebb3/w/4ff7803751f267ccc48c95d1/e/a0e02e37b34b2920f6dd1f5e) enter your width and your heigt (variables at the top) and export as STL.
