First Satellite Cutaway LITE (Sputnik style)

NOT TEST PRINTED. I have not printed this one yet. It passes my software checks (watertight, one body per file, flat on the bed, fits a 220 x 220 mm bed, no supports, parts fit together) and the picture is a render, not a photo.

A free sample of a cutaway desk model. This is the cutaway option of my paid First Satellite Desk Model (Sputnik style), at the same full size as the paid parts. The 64 mm half sphere has a window cut out of the front, and the simplified interior inside it, in a contrasting colour, shows a transmitter block with cooling ribs, three battery packs and a fan. They sit on a small round plinth with my embossed roundel and the word LITE.

It is a display model only, not a toy. It is a generic model in the style of the original, not a licensed replica, and it carries no logos, flags, names or trademarks.

How it goes together

The interior insert sits flat in a shallow round pocket in the plinth. The half sphere goes over it, and its join ring drops into the same pocket. You can turn it so the window faces the front. The insert plate centres the half.

What you get

• 01_lite_plinth.stl: round plinth, 92 mm across, with a shallow pocket, the roundel and LITE, about 24 g

• 02_cutaway_half.stl: cutaway half sphere with the window, about 20 g

• 03_interior_insert.stl: interior insert on its round plate, about 9 g

What you need

• About 53 g of filament in total (estimate), in two or three colours if you like

• About 3.2 hours of printing in total (estimate, not slicer output)

• No supports. Each part prints standing the way it is shown, and everything fits a 220 x 220 mm bed.

The full First Satellite Desk Model has the complete 64 mm sphere in two halves with a joining key, four separate antennas in angled sockets (or 1.75 mm filament rods in ferrules), this cutaway half and interior as an option, and a round display stand with a leaning rod so the satellite floats at an angle.

Honest notes

• Not test printed yet. Fits are checked in software only, with 0.25 mm to 0.3 mm clearances. If your printer runs tight, scale the core or insert down by 1 percent.

• The half sphere is the paid cutaway part with one change: the hex socket for the stand rod is left solid, because there is no rod in the lite.

• Nothing glues or clips the half to the plinth. It is held by gravity and the pocket, so lift it by the plinth.

• The interior parts are small (the fan blades are under 1 mm thick). Print the insert at 0.12 mm to 0.16 mm layers if you can.

• Grams and hours are my estimates, not slicer output.

If you print one, I'd love to see it. Post a make with a photo, good or bad, and it helps me improve the next version.

Happy to tweak the design on request.
