3dr spring socket arms

thingiverse

Using Andycart's innovative cherry pi spring socket joint concept, we'll be modifying it for our third project iteration. Here are the revised instructions: Print all components using a 0.2mm layer thickness setting. Create steel rods by drilling a 4mm hole in the center of a 9mm diameter ball. As for the springs, select ones with a length of 40mm and a diameter of 7mm. Once selected, stretch each spring to achieve an overall length of 80mm
