Based on the shape of an icosidodecahedron (a solid, composed of twelve pentagons and twenty triangles) I used a Christmas rose instead of the pentagon to add some interest, The results you see here.

You can select a hole in the centre of the rose, so that a string, or wire can be used to hang it from the Christmas tree, hence the bauble.

You can alter the size and style of the item, quite significantly, by altering the embossing factor, and selecting whether the roses are aligned by the edges of the petals, or by the 'pointed bits' between them, and also change the size, hence the parametric part of the title.

They may also be illuminated by placing an LED inside, in particular if printed in translucent material, petg or other.

The embossing depth/thickness factor is a value that roughly relates to the thickness of the rose. Values larger than 10 will require a lot more support, and values less than 1 may be too thin for the roses to match with each other, the roses not being exactly symmetrical. I think a value of 3 or 4 looks OK, and uses less filament than higher values, and takes less time to print.

When you slice the stl's, you will most likely need supports. Tree supports will enter the bottom triangular holes and support the top from the inside, which is probably not needed, but normal supports may not do this, if from bed only.

There is no particular filament requirement, silk pla is nice, and if you use petg, say, then an led inserted inside may be interesting.

It is probably better to print in object mode, if printing more than one at a time.
