Number tokens with stackable box

prusaprinters

The tokens can be used for drawing question at exams (that was the design request) or as a game tool.You can fit all 30 tokens together on Prusa MINI plate. And you can add color change to make them more readable.The box has embeded holes for 4x1mm round magnets, so you can stack multiple boxes together. I used superglue for adding them. Just be sure to switch the polarity of neighbouring magnets so you can stack them.I used simple grid:N  SS  NTo be sure you don't switch the úpolarities when gluing second box, just stack the magnets on first box and press them to the hole on second box for gluing.If your printer is not calibrated and you end up having elefant foot on the tokens, they can get stuck inside the box. That is the reason for hole in the bottom, to get them out by finger or pencil.I tested every token by dropping it a few times to the box and back. If it stuck, I used a little sanding to correct it and tried again.
