A small milestone at the roadside has been reached - the first real parts of the kit are in the box, namely for service arm 1 - Element #1 and #2

Above you see the basic arm structure, that applies to service arm #1 to #7, and partly to #8. The First Element mostly stays unchanged for each arm, while the Second Element is more individual, as it carries the Extension Platform, the Umbilical Unit(s) and the Withdrawal Mechanism.

Some of the upper arms have an additional Extension Segment, as they have to be longer due to the Saturn's shape.

The parts for both elements add up exactly to 193. Apollo, patron saint of the Space modelers, may save us from a parts monster. The frame is printed on 100g and 300g red-colored paper, the wire mesh fence on transparent foil. The colored paper secures the laser cut option in any case.

And here are the 100g parts - they don't even need half an A4 sheet.
