An etch a sketch for a 3D pen.
Had this silly idea whith some firends and decided to make it my first real 3D conception project.
About 10 hours of work in Fusion 360 and 36 hours of printing.
Quite happy about this useless contraption.
It might be the cheapest 3D printer ever made but it'll take time and serious dedication to print something presentable :-)
Watch it in action :
Had to add a counterweight at the end of the Y axis to balance it...
Building instructions included !!
This micro-sketch by Ferjerez helped a lot : https://www.thingiverse.com/thing:1668472
Every STL are optimised for 3D printing without support.
Only used support fort the Z axis.
