There are lots of ways to create your own 3D printer, but you might not have considered this one: DIY CNC Router
This simple design from Good Plastic uses a jig saw to cut out a plastic frame, which is then attached to a piece of plywood for support. A motorized router is used to cut out shapes in the plastic, which can then be sanded down into a finished product
The DIY CNC Router kit comes with everything needed to build your own machine, including lots of detailed instructions and templates for cutting out shapes in the plastic. It's also compatible with most standard CNC controllers, including those made by Arduino, Raspberry Pi and others
This project is aimed at kids and teens who want to build something useful but aren't quite ready for more complicated projects like 3D printers. With a little patience and care, anyone can make this!
