Couldn't find any good models of Seliks Prime from Destiny so I designed one myself.
I print this using 0.15mm line height. Everything is flat on the print bed except the outer shells which I print with the outer curved surface up and supports. For the spikes I use a resin printer as this gives nicer results and doesn't require finishing.
Each spike has an indent on the shells that matches the spike size.
The ribs are designed to be a press fit so you may need to sand the sides a little.
Assemble the inner sphere then fit the front disc, then the ribs and outer shells.
I used a glow in the dark blue filament for the disk.
