This Loc Line segment is not being used for a hose. The intended use is as a flexible mount for a small light.
Printed with PLA. Used .2 mm layer height.
To snap the parts together it required some force. I used a clamp. To keep the segments from moving while clamping, I used ΒΌ" doweling in between the segments.
The author remixed this model.
Changed clearance to .02 mm between upper and lower diameters. On my printer it allowed more of a friction fit so the joints would move and yet hold their position.
