In this episode we will be looking at the “Universal Base Designer”, a tool which I whipped as it seems I always need a base for something and especially for vibration reduction (i.e. printed in TPU) so I created this Open-SCAD code and Thinigverse Customizer to solve the problem! There are also some neat tips here like the $FN function to change the shape of the base and a few more so enjoy and PLEASE don’t forget to leave a thumbs UP and subscribe!
