Happy 40th Birthday Voyager!
Here's my desktop model of the satellite. I've carefully broken the design into pieces that can be easily FDM printed. I've intended this design to be printed at 100um layers with a 0.4mm nozzle.
Everything should press together easily, but some dabs of glue could be useful to secure things in place.
There are 14 unique parts. 16 part to print in total. At 100um the total print time is around 8 hours.
I recommend using 100 micron resolution and above as there are some step angles on the antenna reflector. (60% is steepest angle)
No support is required. Some features have minor bridging (<8mm)
All fits should be loose press fit. Glue may help with assembly but should not be required.
