Mechanics
Everything that moves is printed.
The house turns all the way round on a printed turntable and clicks every 30 degrees.
Each cylinder clicks along in 2.5 mm steps, so the boom, stick and bucket stay where you leave them.
Hinged track strips run around real gears and rollers. Two sizes of nose let you tune how snug the tracks sit.
Included
Toy buyers get the guide by email.
Three plates for a 256 mm bed: the house and arm on one, base and tracks on the next, pins and rods on the last.
16 pages and 12 steps, with a check at the end of each one.
