This is a recreation of the Out of This World fun house at Mountain Park in Holyoke, MA. I also included "Big Loo", the giant Celastic robot that Dominic Spadola built based on the Marx robot toy. The robot stood outside the ride and even outlasted it, later placed as statuary in the park. The model also includes the Color Game that stood next to the ride.
This was built for my park model: http://www.karenandjay.com/mtpark/mpmodel/mpmodel.html
Everything should print fine without supports at the small scale for which it was designed (a total of 95 mm across). The Color Game building is tilted on its side to enable the awning to print without supports.
To put the building together, glue the Color Game building to the right side of the OOTW building so that the back ends line up. Glue the building facade (with the flying saucer) to the front of the OOTW building. Glue the triangular scenery piece onto the lower section of the walkway on the left side of the facade so that the wide end of the triangle is even with the top of the walkway. Then glue Big Loo onto the little platform at the base of the triangle. There are holes in the walkway to accommodate supporting posts.
