Serpentine Coil Maker - Extensible, Manual Version

This is a manual extensible serpentine coil maker; an iteration of the previously published model.

This tool is quite complex, requiring many parts, reason for which the assembly is shown and discussion around it is made in an attached document. However, I provide an animation of a step by step assembly  and the tool in action in an animation on my YouTube channel:

For each model, a note gives the quantities needed. In the files section, the components are given in assembly order.

First public version.

Everything was printed using the following:

1. Prusa MK3.9S or XL with a 0.6 nozzle.
2. Prusament transparent PETG
3. Almost everything can be printed with the 0.32mm speed profile with some exception that can be found int the 3MF files provided.
4. Where supports are needed, the organic kind works very well.
5. Despite my effort to print every component, there are a few  screws which are welcome; I used 10 M3x8 and 4 M3x6 screws.

The model was create using OpenSCAD and using the BOSL2 toolkit. The sources are provided in an archive under the GNU General Public License v3.0
