Telescoping Tubes

thingiverse

Inspired by "Extending Tubes" (http://www.thingiverse.com/thing:7081), this redesign aims for less material usage and thinner tubes, allowing greater capacity in a given area. The tubes lock when open or closed, with closed tubes' guides fitting into the adjacent tube track's protruding bump. Open tubes twist to lock over another track bump, providing resistance along the axis. Calibration is crucial for successful printing; start with the 2 small tubes.stl file before progressing to larger tubes, such as the telescope-like largest tube (60mm to 258mm). Post-printing may require knife use to detach stringy bits and slight tube squeezing to free tracks from guides. The project includes NX6 source files for easy parameter changes and additional tube customization.
