This Number Learning Magnet Board includes Number Tiles from 0 to 9 and a Base where a child learns to place all the numbers in the correct spot. The Number Tiles show the digits from 0 to 9, while the Base shows the text version in English ("ONE", "TWO", etc.) and dots that correspond to the value (similar to dice dots). Posts in the Base and matching Slots in the Number Tiles - together with magnets in both - ensure that each number can only be placed in the correct position. This design features neodymium magnets that are safely sealed inside during printing - making this learning aid suitable for use by children over 3 years old.
Each Number Tile is 48mm (1.9") tall by 36mm (1.4") wide by 4.4mm (~0.17") deep and requires two 6mm diameter by 3mm deep neodymium magnets (twenty magnets total for the Number Tiles).
The Base is 242mm (~9.5") tall by 148mm (~5.8") wide by 11mm (~0.43") deep and requires twenty 6mm diameter by 3mm deep neodymium magnets to hold all ten number tiles in place.
I recommend using a magnetic polarity tool such as the “The Magic Magnet Tool” by @tjdesign to help ensure that the polarity of all embedded magnets is the same as well as to make it much easier to insert the magnets during printing. Be sure that all 40 magnets are inserted with the same polarity during the printing pauses!
Note that the Number Learning Magnet Board will still work fine if you prefer not to use any magnets; in this case, simply resume the prints when you'd normally insert magnets.
The following photo shows insertion of two magnets in each Number Tile during the magnet-insertion and color-change pause from the 3MF file after completion of printing layer 17 (3.4mm z height). When all twenty Number Tile magnets are inserted in the Number Tiles, you need to load the filament to be used for the top portion of the tiles (normally a different color)...
The following photo shows the final result of printing the Number Tiles...
The following photo shows insertion of twenty magnets in the Base during the magnet-insertion pause from the 3MF file after completion of printing layer 25 (5.0mm z height)...
The following photo shows the final result of printing the Base...
Please see the attached photos and screenshots for more details on magnet insertion and the filament color changes.
The provided STL files can be printed in PLA (or PETG) and do not require supports. Separate STL files are provided for the Base and for every Number Tile.
PrusaSlicer 3MF files are provided for generic Silk PLA for the Base, for ALL Number Tiles (0 to 9), and for every Number Tile individually.
G-code files have been provided for the Original Prusa MK4 with Input Shaper at 0.2mm layer height for the Base, for ALL Number Tiles (0 to 9), and for every Number Tile individually.
The Number Learning Magnet Board seen in the photos was printed on an Original Prusa MK4 with various colors of generic Silk PLA with a 0.4mm nozzle at 0.2mm layer height with a 15% grid infill.
