Split a double helical gear

Math

Hello,

I have generate a double helical gear using the spur gear feature.

Il would like to split it into multiple part (in order to print it with my 3D printer).

I would like to split it between the folling 2 faces as illustrated below :

The faces have the same angle than the helical teeth and are positionned between 2 teeth (in the midle).

With 2 faces like this, the split function doen't work.

But I have no idea how to do this ?

Could someone have an idea ?

Thank

I believe the split command requires the one entity to split with and for the result to cur the target into at least two parts.

If you extend the surfaces you have such that they also cut through the opposite side I believe that'll indirectly get what you need.

Also I'd probably not bother with sketches and extrudes.  A pair of new planes built around the origin would do nicely.
