The centerpiece of the case is an Arduino Uno board, programmed with various code snippets. This board controls a 4988 stepping motor and a Nema 17 motor, responsible for the kinetic movements.

The beautiful case is printed in a woodfilled PLA — consisting of 70% plastic and 30% sawdust. This allows it to be sanded and stained for an attractive final product.

Like the Arduino microcontrollers, the printer will be open-source. The machine features a print area of 140 x 100 x 100 mm, and a print volume of 1,400 cubic mm.
