As a hobby i do some magic and my Bostonbox was to small for the largest Swisscoin (5 CHF). The effect is much better with larger coins. Feel free to print out your box and amaze others with your magic. See https://vimeo.com/65008178 for a quick example on how to use it.
I had to switch on supportmaterial, but its no problem to remove it afterwards. Add a nice shiny finish using aceton vapour.
