Description

In response to a challenge on the Thingiverse Blog http://blog.thingiverse.com/2012/02/21/oo-someone-make-one-of-these/ I offer this first attempt to print the visual illusion of balls rolling uphill. When viewed from the correct angle, this piece should give the illusion that all 4 ramps slope up to the middle platform. Viewing from any other angle gives the game away!

Nicely done! Thanks for
 making a copy of my "Thing" and proving that it does work!
Might be better cutting the ramps off, and printing with the ball surfaces face down, then using pin connectors or something to assemble. I haven't printed it yet, but I'm thinking the visible layer lines might give the game away?

Instructions

Print the part, then orient it so that you view it as seen in the rendered view, and it should look like all 4 ramps slope up to the central platform.

I haven't printed one yet, but I couldn't resist the challenge!
