Creating a shape with Cura?

[Muckerschmucker 0]

I downloaded Cura to make some shape with an Ultimaker 3D printer. I'm going to start by creating a disk with a small conical hole in the middle for a countersunk screw. On the base of the disk, I'll add some tiny conical points so that the disk grips into a wooden door frame when I screw it in.  I'll print two so I can mount a pull-up bar in the door frame. Figuring I can create this with adding and subtracting 3D shapes. Now, the question is, what menu options in Cura will let me create the shapes to make this work?

I hate to be the one to break it to you, but Cura doesn't make models, it's just for converting existing models into machine code for 3D printers.

 

Edit: I just remembered there's Tinkercad, which is very easy to get into.

What you're trying to do seems like it'd be great to do in FreeCAD, which seems a bit overwhelming at first, but for a lot of things you can ignore 90% of it, the tutorials they have about designing parts are pretty good.

 

There's also Thingiverse which contains zillions of cool (and functional) models other people have made, but probably won't have something as specific as you're looking for.

 

And just remember that the material you're dealing with is plastic, and will be weaker than a lot of plastic things you can buy (most of which are made by injection moulding, where the whole thing sets and binds together at once, not slowly as it gets printed). Different kinds of filament have different strengths and weaknesses, I only really know PLA and ABS, and ABS would probably be better for this use (I think), but I wouldn't count on it supporting that much weight (it's worth a try though, I've been surprised by what other people's creations have been capable of).
