3D model description

Started as a learning project for me but it has turned into a working and usable little electric spinning wheel.
This one is completely designed in tinkercad. But in the meantime I switched to FreeCad. Maybe one day I'll design another one with FreeCad.

Not all parts can be 3d printed for this spinning wheel.
Some parts will have to be purchased.
Also some electrical wiring needs to be soldered, and the voltage needs to be adjusted.
It is not difficult, but some technical insight and experience with a soldering iron is required.

I opted for a USB-C connection because it is fairly common. This also gives the possibility to work with a power bank.
For this, the step-up converter is necessary to increase the speed of the motor with a higher voltage.

The wiring goes from the USB-C connector to the input of the step-up converter. From the output to the input of the speed controller. From the output of the speed controller to the 3 position switch (to allow both left and right rotation) and from the switch to the motor.
I also have connectors in between, but they are not necessary.

Two motor mounts are included so that different motors can be used.

There are also two adapters for the flyer, so that different speeds are also possible here.

I used a rubber band for the string, and a rubber band and a piece of cotton thread for the brake.
A nylon thread is not usable as a brake because it creates too much friction on the bobbin.

All materials can be used for printing, but I personally prefer PetG because of the higher temperature resistance.

Almost all parts can be printed without support.
Only the front and back need support for the recesses where the bearings have to go.

I printed with
nozzle diameter: 0.4 mm
Walls: 5
Bottom and top layers: 5
infill: 15%

For a bobbin, you have to print one tube and two discs.
The bobbins must be glued together. And probably the hole for the axle needs to be drilled (4 mm!).

For a lazy-kate you wil have to print two (or three) stands and one ore two couplers.

For the parts that need to be bought, I have included several links from Alieexpress.
Unfortunately, these items do not always remain available, so you may have to look for a compatable replacement.

Have fun printing, building and spinning.
I would love it if you post a picture of your own built e-spinner.
