Laser-cutting
Laser Cutting on a Glowforge Home Laser Cutter
When all you have is a laser, everything starts to look like quarter-inch acrylic, wood, paper, or resin-free plywood. I've had my laser cutter for a few years now, and I'm really impressed with the scope of projects I've been able to make with it. In addition to flat shapes and engraving, I've been trying to make 3D objects by modeling them in Blender, then figuring out how to cut them from flat planes. It's produced some really cool results.
