It’s time for another design walkthrough. This time we’ll be making polyhedral covers for LED string-lights. Since I’m just a hack at 3D design, for me the answer always involves using a chain of software programs, each of which I know how just enough about to get by, in this case Mathematica, TopMod, and Tinkercad. Each ornament is a hollowed-out instellated Archimedean solid or dual… // Hacktastic

Do you ever get 3D prints that look stringy or lumpy? This week we were seeing a lot of weird-looking prints from one of our Replicator 2’s, so we decided it was time for some holiday hardware maintenance. And wow, did it ever make a difference. After tightening a saggy X-axis belt we’re back as good as new. Tightening the belt isn’t difficult but it isn’t much fun either… // Hacktastic
