Off to the vertical with Lego Duplo!

Those who know me a little better know that my fascination for Lego, Duplo and especially for Lego technique has been preserved until today. Once a year, I have to assemble at least one of these big Lego Technik kits. Here is a small, funny and entertaining hack how to…

We know that an FDM print with 0.3mm layer height is printed much faster than a print with 0.1mm. But…
