This credit card-sized gadget fits perfectly in the wallet of those who may use the Morse Code or want to learn it.
With only 5 grams of material and 20 minutes you could bring the a Morse Code reminder anywhere you want.
Ams is not necessary to print this with two colors (I don't have ams), and it looks great.
Just pause the printing at the beginning of 9th layer and change manually the filament.
