Wind turbine, based on the Archimedean helix

For 30 Cm x 30 Cm Printer Bed

Available Now also for smaller printers Bed 22 cm x 22cm

Update 1/Dec/23

Testing New Rudder (check photo)

Update 9/Nov/23

Video test with motor 5010 (Soon I will make another more robust support for the turbine on the balcony.)

Added STL files for engine base for both versions (28Cm and 20Cm Helix.)
motorBase_280mm.3mf
motorBase_200mm.3mf

Update 19/Oct/23

Available for donwload Zip file "20Cm_V1_1.zip"
this Versión for 22 Cm x 22Cm Bed Printers

Smaller version of the turbine, 20cm diameter, in the assembly process.
Uses the same Bearings as the larger version.
New base with support for Generator (brushless motor 5010 360KV).
I will continue updating and publishing results.

Update 12/Oct/23

Helix For 22Cm bed printers (Now available for download)

Testing printing Base of New Model for 22 Cm smaller printers, Like Animated Gif, printing New Base with Brusless Motor 5010 Mounting and pulleys.

soon available for download...

Update 7/Oct/23

Coming Soon for Download: New Helix design for smaller printers bed (22cm x 22cm)

Working on New Base with pulley transmission to small brushless motor generator.

Check pictures

Update 11/May/2023

***New, added rear support for second oscillating bearing and shaft for pulley

*- fully functional model for educational purposes or small scale builder
*- high revs as it uses bearings for very smooth movement even with little wind
*-very robust design withstands strong winds
*- bearings for both the propeller and the rotating base
*- Precisely shaped washers for propeller bolts

*- to print in PLA or ABS material
design optimized to be printed in 3D, the parts do not require any post processing

Model tested and working as can be seen in the photos and video.

includes future updates

30Cm x 30Cm bed

NEW 22cm x 22Cm Bed Version

0.2 Layer
PLA or ABS filament

**No supports for helix (the helix already includes support, it is not necessary to add it in the laminator)

For the base and bracket of the fence, use a tree support and print in the position shown in the photos. motor base and deflector does not require the use of supports in the laminator

Extra Materials

*- Zinc-plated Threaded Rod 3/16" one meter long (I cut it into 14 cm long pieces for the screw of each blade)

*-Hexagonal Nut 3/16" Galvanized X 18 Units

*-H° Flat Washer 3/16" X 18 Units

*- Two oscillating ball bearing 1202

*- Two bearings 6005

The turbine printed in PLA+ is very robust and withstands very strong winds.

Now testing with Brushless motor model 5010 360KV as a generator.
I will post result soon

Parts:

for both versions use the same bearings

2 oscillating bearings 1202 (for the turbine shaft terminals)

5/32 threaded rod for propeller screws

I bought a 1 meter long screw at a hardware store and cut it, you also need:
18 nuts 5/32"
18 Washers 5/32"
print the plastic washers to align everything

To join the propeller shaft and the rear base of the shaft I used this screw and nut kit

As for the pulleys, I am still waiting for the motor that I am going to use as a generator, I have not done the tests yet but I leave you the links of the ones that I am going to use.
