i printed the mini printer with 10% Infill, the spring with 100% infill and the base with 30% infill. i strongly recommend using support to print the printer.
i used the Parametric Bobblehead Bases and the Parametric Bobblehead Springs from 3D Printy (https://www.printables.com/de/model/307138-parametric-bobblehead-bases)(https://www.printables.com/de/model/282561-parametric-bobblehead-springs)
