I had the idea to try and create a way to easily demo how the Ames Window works.

Here's a video that demonstrates the illusion quite well: The Magical, Mystical,  Mind-bogging Ames Window by CuriosityShow

Parts:

• 2x Base (The top and bottom are the same)
• 1x Hook Disc
• 1x Hook Disc Crank
• 1x Shaft
• 1x Crank
• 1x Holder Bar
• 1x Ames Window Two-Sided
  • ~or~  2x Ames Window One-Sided (and some glue)
• 2x Pieces of thin, preferably transparent, string-like material (like zip ties or fishing line)

Notes:

• Some of the pictures are outdated.
• Use a layer height of at least 0.2mm
• Please use supports wherever you can. 
  • I tried to make the whole thing work without them, but it's way safer for tolerances if you spend the extra time.
• I used the ‘two-sided’ Ames Window for this first print. This model is a little iffy and requires the use of supports.
• It's way easier to do multi-color on the one-sided version, although I don't know how well.
• Using ‘normal’ string to suspend the window may make it more difficult to rotate. So, I recommend using something thicker, like zip ties (what I used) or fishing line (the other photo).
  • (Maybe rubber bands would be a better fit. Or just a giant vertical pole…)
• You could totally use the floating frame for something else. Maybe even jewelry.
• I'm always welcome to suggestions/edits if you'd a specific change to be made.

I could tweak the design and tolerances of these models forever, but for now, this should be ‘enough’.
