I'm building this 3D Printer for my next project, a mostly 3D Printed E-Foil. That's why I need a 40³ build volume... in hindsight, 50³ would have been a better choice.
I want to print really strong materials with this printer, like REALLY strong. We'll see how that works out.
I'll release a build manual as soon as I'm done with my 3D Printer.
