Wanted the tokens to be protected and feel better in the hand. I printed these at .16 layer height, but I'm sure .20 would be fine. I suggest putting the more “rounded” side of the token (left token in photo) down into the smaller side of the capsule, then close the larger side over it. Very tight fit, I had to use a flat tool to close them.
NOTE: You may want to scale up 1% or 2% according to tolerances, mine were VERY tight to clip together and will literally never come apart. My wife complained and refused to help me close them all it was so tight lol. But I wanted a perfect fit personally. I'm quite happy with them. Suggest test printing a couple in different scales to your preference.
The author remixed this model.
Increased size and modified for thicker tokens.
