Micro Bungee for TPU Filament

Turn a spare few cm of your TPU filament into miniature bungee cords. You can make a straightforward bungee cord with two hooks, make a simple strap with one buckle, or mix-and-match to create any manner of web or net. The unique E-Z Cinch attachment mechanism is easy to adjust and tighten, making this a great alternative to single-use zip ties. Prints easily in PLA with 0.2mm layers. Both hook and buckle use less than 1/2g of filament. To use, poke one end of your 1.75 mm TPU filament up through the slot and pull taut, loop around the U-channel maintaining tension on the cord. As you tension the cord, it gets squeezed between nubs at both ends of the U-channels, holding it securely at two points. Finally, tuck the free end back through the slot. Happy bungeeing!
