Today is Pi Day (3/14 because the date matches the first digits of pi, 3.14). These Pi Spirals that I made with the Creality Falcon A1 Pro are something fitting for this occasion:
The cork coaster and the keychain were made with the diode laser module and the brass coin with the IR laser module.
If you also want to make similar engravings, you can generate these Pi Spirals with this generator and export the SVG or PNG.
