3D model description

This is an OpenSCAD version of the excellent e-liquid mixer "The Harduisteeper" by PeterCo014:
http://www.thingiverse.com/thing:1987389

The micro servo 9G model used is done by TheCase, with some slight modifications:
http://www.thingiverse.com/thing:29734

It is an amazingly effective and cheap mixer for two e-liquid bottles (30ml to 50ml). It works even with 100% VG mixes.

I had a bunch of "el cheapo" Arduino mini 168 laying unused in a box, so an adaptation was needed to fit this model.
Having it in a parametric form also allows easy modifications and adaptations.
See the source code for comments on options.

Hardware needed:
- Servo motor: Micro ("9G" type)
- Ball bearing: 10mm ED, 3mm ID, 4mm width (can be adapted in source code)
- Arduino Pro Mini 168 "Baite" (for example: https://www.aliexpress.com/item/1pcs-Pro-Mini-328-Mini-ATMEGA328-5V-16MHz-Free-Shipping/1432585134.html )
- A micro-USB PCB (for example: https://www.aliexpress.com/item/10pcs-MICRO-USB-to-DIP-Adapter-5pin-Female-Connector-B-Type-PCB-Converter/32720363831.html )
- A common cathode 5mm RGB LED
- 3 resistors (2x470R + 1x560R)
- 4x round foam pads for feets (37mm diameter), optional
- Some screws (see source code header comments)

I included my quick adaptation of PeterCo014's original Arduino code.
My version has a pause between cycles and the movement speed is ramped progressively. Feel free to contribute modifications...
The comments are in french, as they were in the original file, but I can provide a translated version if needed.
