RCLifeOn created a 2D drawing lightbox from an old 3D printer, a marker, and some LED lights to draw patterns on acrylic. Even more interesting, he did it live on Twitch.

Like many creators, they’re finding a tremendous amount of free software to complete projects without needing to invest long hours developing their own software. They’re creating increasingly more amazing stuff from off the shelf parts.

Some of his software tools:

• Autodesk Fusion 360 for drawing up the 3D parts he needed
• Sandify is an open source java package that creates patterns/paths for robots to draw in sand (continuous lines without lifting, etc)
