Maker Update: Contraptions and QR Coasters
by Mark Frauenfelder from on (#3FX17)
Every week Donald Bell posts a video about interesting maker projects. This week in Maker Update he looks at an animated wooden sign, new mesh boards from Particle, 3D printed QR coasters, 3D printing on fabric, and his talk with CNC router whiz Jon-A-Tron. This week's Cool Tool is a Retractable Cardboard Cutter.
