Nails and Screws Reimagined with 3D Printing

3D printing technology can enhance the traditional nail, a versatile connector that has been in use for millennia. A proposed innovation is a nail with an internal channel along its shaft that exits at the side. Once inserted, a smaller nail can be added to this channel, providing both longitudinal and rotational anchoring. Screws would benefit from this additional reinforcement as well. This connector's extended channel could also be utilized as a wall anchor or a conduit for wiring or fluid. The exit port offers control over the direction of wiring or fluid flow.
