I designed this desktop mount for raymarine st60+ instruments. I needed it to be able to test the instruments in my home before I put them in the boat. The print is stackable horizontally (M3 screws) next to each other and there are also holes for the cables to run through. Also there are holes in the bottom to screw it on your desk (M4/M5 holes).

You can add support if you want. The printer can still print the big arc of the whole of the instrument but it's not gonna be perfect. I just do it without support and then file it a bit with a file to make it pretty. If you don't care about resources you can use supports.
