Ten frame magnetic math instructional tool
thingiverse
This is a prototype for an innovative "ten frame" math instructional tool designed specifically for students and educators alike to utilize in a hands-on manner. The model features adjustable markers that are securely held in place by powerful magnets, ensuring uniform visual presentation and precise positioning. These magnets also enable the ten frame to be displayed vertically without any risk of marker displacement, while allowing it to be easily mounted on magnetic surfaces. To create this device, we recommend using a 3D printer with fine slicing capabilities (0.3mm), printing four perimeters, four shells, and a 15% gyroid infill. The frame should be printed in the same orientation as intended for use, while the markers are printed upside-down to accommodate their position on the ten frame. The device incorporates fully-encapsulated neodymium disc magnets (8mm diameter x 3mm), which must be carefully installed during printing to ensure proper alignment. To avoid any issues with magnet placement, pause the print before completing the encapsulating layer, install the magnets using a small amount of glue, and then continue printing. It is essential to double-check the magnet orientations to guarantee that the markers are positioned correctly on the ten frame. For optimal visual appearance, we suggest changing filament color immediately before printing the dividers and the visible side of the markers.
