Two-turn Möbius strip

[kandennti]

Hey everyone.

A Möbius strip is made by twisting the rectangular sides 180° and attaching the ends to each other.

If you turn it around twice and attach the ends, it will look like this.

As it is, there is a self-intersection.
If you drill a hole to remove the interference, it will look like this.

I have created an add-in to create this shape.

It may not be useful for your design.
However, you may enjoy it for a little while.

I carved this out of chemical wood.

Can you give us more information about this process?

I think you should add the ConstructionPoints filter to the SelectedCommandInput object so we can directly select the origin without creating a sketch first.

In MobiusStripCore.py:

_point = SelectionCommandInputHelper(
    'pointIpt',
    lm.sLng('Center Point'),
    lm.sLng('Select Sketch Point'),
    ['SketchPoints', 'ConstructionPoints'])

Thank you @TrippyLighting .

It won't help you, but I think you will enjoy it.

I forgot to attach the video.

Thank you@JeromeBriot .

Since my company only has a 3-axis machining center, I divided it into 5 pieces, machined them, and glued them together.

I'm thinking of a way to machine it without splitting it, but I can't come up with a good idea.

@JeromeBriot .

The reason why I used only points in the sketch is because I needed the direction of the plane. That's why I couldn't use ConstructionPoints as a filter.

I completely skipped over the fact that you created a plugin. Incredible! 

As you also made the "thing" this really captures the essence of Fusion 360!
