User Created Custom Parametric Shapes
I'll first just start with PrusaSlicer is amazing. I have been using 2.3.0 and love the new features. One feature I would like to see added is the ability to add custom primitive shapes that can be called on for any print. Specifically, I would like to add a "thermal tower" for when my prints have small features that stick up and get too hot. The box shape could work except I would like the tower to be as small as possible. I found 2mm to be the best size for keeping the head away from the model long enough to let it cool. If I create a 2mm box though, its base is far too small to stay connected for the entire print. I created a model in Fusion 360 with a wide base and a 2mm tower that rises off of that, which works well. I realize this is and should not be the highest item on the priority list. Honestly, if someone could tell me where the other primitive shapes are defined, I would be fine with figuring out how to add my own.

Right click on bed, add shape, box, unlock and resize to 25x25x2.
Right click on box, add part, box, unlock and resize to 2x2xdesired height.
Move both to suitable position on top of each other and slice.
Cheerio,

I did try that. The slicer sees them as two different objects to slice and overlaps the layers. The print results are pretty nasty.
I did off-center the box a bit so you can see the results. The centered version looks ok but tries to print two layers in the same location, which doesn't go well.

The bit you are not following from the above explanation is the right clicking on the original part when you go to add the second. If you just right click on the bed a second object is added. When you look at the tree list to the right you will see 2 separate objects listed.
By right clicking the original added Object and adding a second you will add a second PART to the existing object. At that point the tree view will list 1 object with 2 parts. Slicer will then slice them as one object, so it wont try and put 2x as much plastic into the areas where they over lap.
The placement rules also change as a part can be moved around freely as long as some part of the total OBJECT touches the bed. Its the difference between Objects and Parts.

Ah, thanks so much. I had no idea that was a feature. Sorry for not paying close enough attention to the instructions.
