I printed the back without any top or bottom layers as I thought it would look cool but don't have to do that.
All models should already be oriented in the position I used to print them. You should not need supports.
I remixed this as I couldn't find a picture frame that would fit my exact dimensions.
Happy printing!
The author remixed this model.
I have changed the dimensions so it will now fit a 180/200mm picture.
