Loop Strap – A TPU 3D Printable Strap for Your Outdoor Adventures

Inspired by the MODL Infinity Tool strap, this redesigned version has been fully optimized for 3D printing. The Loop Strap delivers nearly 8 feet (240 cm) of flexible TPU strap in a single print yet fits within a 210 mm × 210 mm build area, making it compatible with most standard 3D printers.

You can cut the strap to any desired length and use the included Basic Closure to connect both ends. Just like that, you’ve got yourself a strong, versatile strap for everyday carry or outdoor adventures.

Notes

This is an ongoing project — I’ll be adding more closure styles over time based on testing and community feedback. The included STP file is there so you can easily create your own custom closures.

If you make your own version, please share it back on Printables — I’d love to see how you use and improve the design.
Have fun printing, and enjoy your next adventure with the Loop Strap!
