There are two types of frame backings.

The “Magnetic Circular Frame Backing” is a low profile backing intended for use as a fridge magnet. There are holes for four 1/4” x 1/8” cylindrical neodymium magnets. This frame backing uses the least amount of material and is fastest to print.

The “Multipurpose Backing” has holes for four magnets, as well as holes for mounting with screws and holes for inserting supports to allow the frame to stand upright on a flat surface. To use as a stand, you will need to print two “Frame Support” files.
