MatePlotter

This is a work in progress project. The models are currently tested and will be updated, along with arduino sample code.

What to expect

This is a 2D Plotter for mate glass bottles, that uses the very common 28BYJ steppers. The goal of this project is to give programming beginners a fund and practical exercise, by writing code for microcontrollers to draw shapes and sketches onto the bottle.

How to use

The MatePlotter uses a common GT2 belt and 8mm round aluminium rods. Pulley and idler for the belt assembly are printed. You should be able to assemble everything with only M3 and M4 bolts and nuts. The 28BYJ steppers are mounted inside the base to actuate the turntable and the pulley. To use the MatePlotter you insert a standard 0.5L glass bottle and put a pen into the carriage.
