We made these little pins for our friends out of 2mm EVA and Worbla.
2mm EVA settings
Engraving - 1000/12/340
Cut - 350/20/3x
Edit - Oops, completely forgot, if using EVA, heat seal the foam first! Before putting it thru the Glowforge, use a heat gun and pre shrink it. Low settkng until it’s a tad shinny on both sides.
Eva is on my list of materials to try. Why heat seal? How does it react with or without the heat seal? Is the worbla for strength or stiffness. Great design btw.
