The LEGO led light is printed in Overture Clear PETG. The base is fastened to the main body using 4 - M3x0.5x 6mm screws. The main body utilizes 4 - M3 threaded inserts to accept the screws (one at each corner). There is a tab at each corner of the main body that accepts the threaded inserts. Supports are required when printing the main body since the corner tabs are 2.5mm above the build plate. The led light ring is supported by 4 posts on the base and is held in place with the clamp ring. The clamp ring is secured with a M3 screw which screws into a threaded insert in the center post on the base. See the images of the base with the light ring mounted. Note that a cable tie laces through two holes in the rear post and secures the wire.
