These are the pieces for my Altoids Tin Chess Board
They are meant to accept 4 mm X 2 mm disk magnets. You can find these cheaply from China on eBay in quantities of 500 for less than $10. I was trying to figure out how to make a magnetic chess set without using a stupid amount of magnets. It occurred to me that a flat steel sheet would work, but I had none. These tins on the other hand, I have tons of. They only cost a few dollars anyway and come with mints.
I suppose you could also toss them on a fridge or the hood of your car.
The pieces fit upright with the lid closed just fine. They measure about 7 mm diameter at the base of each piece.
Don't forget to pickup the board as well.
Thanks go out to PerryT for the original models.
I recommend using the tweezers made by MechEngineerMike
Thanks go out to him for making cool tweezers.
0.4 mm nozzle w/ 0.2 mm layer heights
15% but they'll probably be solid anyway
Be careful removing them from the bed.
