Bowden clamp with a blind rivet nut (not printed)

thingiverse

To reduce bulkiness, I replaced my traditional printed bowden clamp with a blind rivet nut. The innovative design includes a helpful shoulder that fits seamlessly into 3D-printed components. This results in an incredibly sturdy connection. To make installation easier, sand the tube to improve grip and thread penetration. Use pliers to securely hold a rod or nail of appropriate size before attaching the nut.

Interestingly, these nuts can also be used within printed parts for strong and tidy threads.
