There are a lot of DIY CNC projects out there (router, laser, 3D printer, egg drawing, etc.), but I never saw a DIY CNC sandblaster. So I decided to make my own.

Hardware

The CNC frame is one of those cheap kits that you can get on ebay for instance. Mine was around 200 euros, and it is actually a good value for the price. I built the kit and then replaced the electronic controller with an STM32F469 discovery board and an arduino CNC shield.

For the sandblaster itself, my father and I hacked this simple solution made from a soda bottle and pipes/fittings that you can find in any hardware store.
