Star Trek Communicator

Communicator from Star Trek: Beyond

I used silky filament to get the brushed metal look.

The body is centered at the origin (there is a small piece to prevent autocenter if is enabled) and printed with the "Archimedean Chords" top fill pattern (in PrusaSlicer), which is an spiral (but almost look like concentric circles). The dial and the inside piece are also printed with the same pattern.

The "inside" part (that does not appear in the photos) goes behind the glass lens. In between, you can use a blue filter to tint the lens (I used some pieces of plastic cut out of a dishwasher rinse aid bottle).

You need to print 2 "dial_aligner", 4 "back_aligner" for aligning and gluing the dial and the back

And 2 "grid" to close the emblem holes on both sides of the cover.

In the "body" and "cover1" there are small holes to add neodymium magnets (2 mm diameter, 1 mm high) to hold the cover closed.

Everything can be printed without supports, except for the hinges on "cover1 ".

You can find the holster here:

The grids are printed using the "grid" part with "Honeycomb 3D" infill pattern and 0 layers for the top and bottom shells.
 

To make the lens I used the "sphere_cast" part to create an alginate mold and filled it with epoxy resin. Once cured I sanded the base and then attached the lens to the "sphere_polisher" piece (with double sided tape) and sanded and polished it with the help of an electric screwdriver.

Another (easier) option is just print the "sphere" piece with clear petg, but it will not be as transparent.
