thingiverse
A Mickey Mouse shaped picture frame. The "portal" diameter is 90mm (about 3.5in) and nicely hold a picture with a diameter of 101.6mm (exactly 4in). I cut my images from a 4x5 printed photo to size using the included "disk.stl" file as a template.
There is nail hanger on the back of the frame.
For the "glass" cover, I placed a 4in diameter, 1/16in thick acrylic disk in front of the picture. These can be purchased from amazon (or elsewhere) for about $10/pair.
e.g. https://www.amazon.com/gp/product/B07L6MLPFN
The picture is held in the frame using cardboard cut from a shipping box and a 3D-printed bar that holds the acrylic, photograph, and cardboard in place. The bar is the white rod in back facing image that I uploaded.
