Magnetic Trefoil Knot

thingiverse

A hobbyist's passion project: crafting trefoil knots using tiny neodymium magnets. Instructions are crucial for completing this time-consuming endeavor, requiring: 48 small ring magnets (neodymium, 3/8" x 1/8" x .060") Epoxy as a bonding agent Assorted tools like binder clips, C-clamps, parchment paper, cotton swabs, fender washers (7/8"), and diamond files. Each magnet pair should be scored with a diamond file before assembly to ensure epoxy adhesion. Magnets must be spotless and dry before handling. A cotton swab is used to apply a small amount of epoxy into recessed holes, utilizing '+' and '-' markings for reference but not necessary. Fender washers keep magnets flush to mating surfaces, while binder clips secure them in place during curing. Parchment paper serves as release material. Follow the fender washer/parchment paper/binder clip method, adding magnet pairs to one end of eleven pieces only, excluding the last piece. Once epoxy is cured in the first batch, use magnets with parchment paper between adjoining pieces to position paired magnets, aided by tape for memory retention. For assembly and positioning, utilize C-clamps under low pressure, as excessive force may lead to disorientation. Careful planning and slow work are essential for success. Disassembly and reassembling are part of the fun: once complete, disassemble and try to put it back together using the magnetic fields alone – a thrilling challenge indeed!
