2 Introduction

The construction set 3Dsimo Kit is an open source project, which intends to familiarize people with a

wide range of possibilities when drawing with a 3D pen and give an opportunity to the user to modify

and expand functions of the pen according to their preferences. Considering that the base version of

code is available through GitHub https://github.com/3dsimo, anyone with minimal programming skills

can modify it. The heart of the Kit a is slightly modified Arduino Nano-like board, which controls the

whole board and functions like material extrusion after heating up the heating element to the

temperature set precisely by a PID regulator or displaying the status information on the OLED display.

Out of the box, two pre-set profiles can be set for ABS and PLA and more user material profiles can

be added to the code.
