3D model description

This ball allows 3 tubes to be fixed at right angles.

The idea came to me because my son wanted to make a bamboo hut. The first attempt with string failed miserably; the knots could not hold. So here is the solution.

Or why not make some nice bamboo shelves - if you have a garden, it grows very, very fast (and it spreads attention).

The model is dimensioned for Ø24. This also goes for smaller diameters. Just tighten it a little bit. Otherwise you can wind something on the tube (a piece of inner tube for example). You can also print the object with a zoom factor, smaller or larger...

The v5 has a cavity that allows the use of a shorter screw that does not protrude. (the v4 has no cavity)

3D printing settings

Coat thickness 0.4 (or 0.3 for a better finish)

5% (or 10%) honeycomb filling (it is more solid)

Brackets: yes
