Greetings from South Carolina

New user here. I have a PRUSA MK3S and I've mostly been printing other people's designs that I find online, but I'm at the point where to get the most out of my printer I need to be able to design for myself.

I looked at other options but settled on FreeCAD. Seems to be very powerful but not as user friendly.

I'm working on a project that is a cylinder of specific dimensions with a groove across the top face and a chamfer on that face. I can't for the life of me (in spite of an enormous time spent on google) figure out how to make the groove. I've done some tutorials but none seem to address this in this way.

Any help would be appreciated.

TIA!

Sort of nebulous description.

But, for study, here is one interpretation done both in Part workbench and in Part Design workbench.

The second from the left is what I'm looking for. Don't need the hole in the middle though.

Other than size and made in different workbenches they are the same...

I would:

In Part work bench
Make a cylinder to match the outside diameter
Make a second cylinder to match the inside diameter
Make a Boolean cut to produce your hollow cylinder,
Make a cube the width of the required groove
Elongate it so it longer than the outside diameter of the cylinder
Position it to the correct depth of the groove
Make another Boolean cut
Then create your chamfers.

Hope this is what you are looking for.

where exactly to make the chamfer: on the edge of the cylinder, on the edges of the groove, the 2?
you have to be precise, a tool exists in each of the workbanch

Would you mind changing the subject of the first post to something more descriptive? It is also the name of the topic which is used for searching.
