Jeff 3D-printed this 28mm-scale Type 6 shuttle, as seen on Star Trek: The Next Generation. The paint job looks a bit messy close up, partially because you can make out the print lines and also because the Screaming Skull paint I used for the shuttle body is rather lumpy, defeating my efforts to paint multiple very light coats. On this side of the shuttle, you can see that I used weathering pencils to write in the shuttle name and registration by hand.
On this side of the model, I painted "1701-D" using a very fine brush. I think the pencil was the better approach.
The tinier the type, the greater the challenge in making it legible.
Keen observers will see that I didn't even attempt to add the red pinstripes on the port and starboard sides that contain the shuttle number and parent ship name indica, nor the tiny Starfleet delta. If I can find proper decals at this scale, I'll add those pinstripes and replace my clumsy lettering on other parts of the ship.
