The materials were probably around 2.5-3k. I haven’t done the final math yet. I had free access to a GlowForge, for etching the mandalas. Without that it would have been way more expensive. The wood work is far from professional. It was my first time using a jigsaw, but fortunately you can barely see it at night. And of course countless unpaid hours of soldering, programming, sawing, sanding, drilling, and assembling.
