Can I play it the other way around? I have a 3D printer and I have Flexbot. Then I came across the idea that I can turn Flexbot into something else, which can be fun as well as cool.

The electronic part of Flexbot is based on Arduino and it’s open source. Many potential uses can be applied to the PCBA board. Flexbot is an application for flying in the air.

But many specific
