Clamp that is designed to be used in tube-in-tube (or "rør-i-rør" in Norwegian) tubing systems. The clamp has been specifically created to be compatible with Roth's 25mm tubing, but it is possible that it may also work with other types of tubing.
Use a ordinary plywood screw to fasten them.
Printed using PLA, but for longivity reasons you might decide to go with petg, ABS or ASA?. But as far as i can see my PLA stands up fine to the flexing. Also this is mounted in a dark area. Lifespan of the rør-i-rør is 90 years(ish). So you need to evaluate yourself if it is ok. :)
