Crane with boom that raises and lowers, hoist that raises and lowers and house swings. Total boom length is 24". Boom bolts together with #4 machine screws. The drives are Technic motors and controllers. Most parts will fit on printer with at least 8" print area. Track frame and house frame require slightly larger print area. The swing drive is 3 stack-able planetary gear assemblies designed by ProfessorBoots https://www.printables.com/@ProfJohnny_823077 and with a 1/64 total gear ratio.
Will also need bearings for the point sheaves, hoist and boom drums and drives, and load block. Grooved bearing were used for the boom cables. The turntable bearing is a 6" lazy susan bearing purchased from Amazon.
