Xrot Bolt, Nut & Bit 21x36mm

This collection of Bolt, Nut & driver Bit have been designed from the ground up specifically for FDM production, leveraging all the structural advantages of the manufacturing technique to create a cost-effective fastener that is superior to all other manufacturing methods per weight of the same material.

The design of the socket and drive have also been created specifically for FDM and perform far better than a standard hex or torx design. The geometry has been optimized to the highest level providing unparalleled precision and fidelity.

Original source files are included, and the technical design specification of all critical dimensions.

2026-01-16 Update: Added STLs for individual components to streamline production.
