This is a 3D printable model for a "ten frame", a math instructional tool. It is intended as a physical manipulable device suitable for students or teachers. The markers are held in place with magnets, and auto-center for consistent visual presentation. The magnets allow the ten frame to be held up vertically without losing markers. The magnets also allow the frame to be mounted to a magnetic surface.
Slices fine at 0.3mm, 4 perimeters, 4 shells, 15% gyroid infill. Print the frame in the same orientation as it will be used, and print the markers upside-down. The frame and the markers hold fully-encapsulated neodymium disc magnets, 8mm diameter x 3mm; the magnets must be placed while printing so they are fully encapsulated (pause the print before enclosing layer, install the magnets with a drop of glue, continue). Be sure to double check the magnet orientations so the markers position correctly.
I recommend a filament color change immediately before the dividers are printed, as well as for the visible side of the markers.
