Kinetic wave for your Benchy

This fully printed mechanical wave will allow you to sail your favorite Benchy.

Most automata of kinetic wave are linear. I inspired from these to create this circular version.

The mechanism is pretty simple : the first wheel hold the wave and turn anti-clockwive while the second wheel hold the pales and the boat and turn clockwise.

I added a reduction gears system on the crank so it is easier to have a smooth rotation.

If you look under the central water lily you will notice the three little fishes swimming.

You will need to use sandpaper to smooth the wave otherwise there will be too much friction and the all thing will be blocked (see “instructions”).

You can use a Benchy scaled from 90% to 110%.

(I used a 110% scaled Benchy for the pictures).

Print Settings :

• Printed on MK3S - PrusaSlicer 2.5
• Nozzle : 0.4mm
• Filament : PLA

- Plate 1 (Support) : 0.3mm z-height

- Plate 2 (Wheels) : 0.3mm z-height

- Plate 3 (Crank and feet) : 0.3mm z-height

- Plate 4 (Pales and boat clip) : 0.3mm z-height

You should start by printing 1 pale and check if the tolerance is ok. It must move freely in a slot of the "central Wheel". If it's too tight you can try to reduce the width at 98% (or lower) but you must not reduce the lenght.

The “Boat clip” has a very small first layer. Maybe you should print it alone not to fail the all plate of pales if it unsticks.

- Plate 5 (Fishes) : 0.2mm z-height - Color change at 0.80mm

This part must be printed in 2 colors

I use External perimeters first for more precise engravings

- Plate 6 (Water lily) : 0.2mm z-height - Color change at 0.80mm and 9.20mm

Colors used : Jet Black (Prusament) - Viva la Bronze (Prusament) - Azure Blue (Prusament) - Green Grass (Filamentum) - Lipstick Red (Prusament) - Traffic White (Filamentum)

I added Gcodes for the time estimation. You should generate your own.

Instructions :

• 1- Use sandpaper or a file to clean every steps you have on the wave (left picture). You will need a perfectly cleaned wave to enjoy a smooth rotation (right picture).

• 2- Clip the 3 studs in the support, then clip the feet.

• 3- Clip the “Crank Handle” to the “Crank” (use the “Crank clip 1”). Insert it in the support going through the “Crank Wheel” and the “Crank Wheel 2”. Put the “Crank Wheel 3” and add the “Crank clip 2” to the end.

• 4- Put the “Wave wheel”, the “Central wheel” and the “Satellite wheel” on the support.

• 5- Put the pales. Make sure every pale is correctly inserted in the wave.

• 6- Add the “Fishes” (there are 4 little studs to put it well). Add the “Water lily”.

• 7- Choose your favorite Benchy and glue the “Boat clip”. Clip the Boat on the pales.
