A very simple, lightweight picture frame quickly (and roughly) designed in Fusion 360. Parametric enough to adjust to 7×5 prints, but probably not much beyond that.
2 sample GCODEs provided, one for each orientation; layer height has minimal effect, as does infill (because there hardly is any).
Landscape tolerances have been tightened slightly from the model photo.
The author marked this model as their own original creation.
