A frame intended for small photos or artworks which will either sit on a separate stand, or be stuck on with magnets. To save material and printing time, the parts are hollow, with walls of selectable thickness. The frame is in two parts – the actual frame, and a backing piece or “block” that snaps in to hold the artwork in place without gluing parts together (though you can glue it if you wish, of course). The model is designed for easy printing – the pieces are correctly oriented in the STL file, and generally you will not need a brim or supports (see below for exception).

Note: the project Parameterized Picture Mat by Tyler Tork is useful in conjunction with this model.

Parameters

• The size of the space to leave inside for the artwork (including depth).
• The width and depth of the frame border.
• The size of the ledge in the frame to hold the frame contents in from the front.
• How far back the contents will be set from the front of the frame.
• Whether there will be magnets on the back, and their type (cylindrical or magnavinyl).
  • If cylindrical, their number (3 or 4) and dimensions.
• The thickness of the walls and backing material. A larger frame should have thicker walls, so it doesn't flex too much.
• Whether there's a cutout or “recess” in the back. You may want the cutout to make part of the back visible (small artworks often have artist information on the back), or just to save even more material. A recess can be used to hold an artwork which is dimensional or smaller than the frame, as in the sample photo where the small watercolor is held in a shallow hole to keep it centered without adhesive, with a clear cover to hold it in from the front.
• The shape of the cutout or recess – rectangular, oval, or custom based on an SVG file you import (NOTE: SVG import doesn't work in the MakerWorld paramaterizer… yet).
• The width and height of the cutout, and if a recess, its depth.
• Whether to make the back of the recess solid, or just a little ledge to hold the artwork in place from the back.
• Whether to add “sawtooth” hangers on two edges of the frame to let it hang from a pinhead or small nail, and how big to make the teeth.
