[SOLVED] How to make a hole in a tapered, extruded object?

[SteveDee]

how to make this 2nd boolean cut

Better not to mix Part and PD WB's.

OK, I will remember in future...

Make the Boolean between Cut and hole7mm.

Thanks Bance, I tried that combination but it seems to block both holes, so I must be doing something wrong.

Thanks to all other replies, but I want to do it this way initially (if its possible) before moving on to other techniques. After all, boolean operations are important ...and at the moment, I'm just a very confused beginner!

OK, its not blocking both holes...its about what is selected in the tree view.
I can see the 3mm hole, but still not the 7mm...

Tinker around with the visibility of the extrudes in the link group, It looks like you've fallen foul of the apply/OK gotcha.(only one!)

Well, I managed to view, export and 3D print this object OK, but I got a fatal error message...

Is this not sufficient ?

Lots of alternatives, but are compound boolean cuts known to be problematic?
