Using the Base Magnet Print:
This is a FREE work-in-progress for fans who would like to add STRONG 5mm round magnets to the underside of their existing designs. It works with all standard 130mm by 130mm designs.
Place the magnets into the holes, but do not glue the magnets themselves. Instead, glue the rest of the base around them, allowing the magnets to spin freely in place. You may also find that fewer magnets are needed than the design provides.
