Picture Frame for Mini Lithophane Light Box

This is a picture frame designed to frame a mini light box and a 3D printed lithophane image. The mini light box can be purchased here: https://www.amazon.co.uk/gp/product/B0767LGTZM/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 This design is inspired by Ryborg's frame but has been completely remodeled in Fusion 360 and SketchUp 2018 to produce a perfectly clean model. I have included the corner section model in both Fusion 360 and SketchUp (V8) formats within the files, allowing you to change the model ratio by scaling individual sides and then mirroring the components to create a custom-sized frame.
