Update 16 dec: added variant of decoration. if you prefer to attach it with a hook.

For information about PrusaSlicer:

I used the parameter Infill “lightning” for the support, it's amazing how you can save filament with this option. I highly recommend. 

I used also the new option “Hilbert curve” for the top layer infill and it looks very nice.
