In my world – 3D printing and light weight vehicle electrification melts together. In order to be one of the first persons in the world who builds custom design electric bikes / trikes out of recycled materials – I need some tools. Those tools aren’t very new, but not yet upscaled and affordable enough to meet my intentions. So I decides that I have to buil giant 3D printer myself. Than I need appropriate software, tools to make filament out of reused plastic pellets and tools to work with batteries. What I can achieve with those tools should spark many things those can help fight global warming in fun , practical and educational way.
