Pole illusion - Educational Model

Hello,Inspired by an item I saw at the Children's Science Museum, I decided to create something similar.The calibration of the printer must be perfect in order for the item to work perfectly.I used tree supports. Be sure to remove all the support material and sand the area if necessary.This fascinating desk toy illustrates the strange property of a straight rod that fits perfectly through a curved hole when rotated around a central axis. It's a simple illusion and it's really satisfying to watch!Boost MeIf you enjoyed this model, please consider boosting it to support me to further develop nice designs, Thank you! I would love to see you share images of your prints Thank you,
