Spinning Illusion v.2

Update 14/11/2023:

I split the rod from the base with the effect, creating a much more solid screw connection, with 4 perimeters!
If you've already printed the old version, you only need to print the following profiles:

Rod.3mf

Illusion1.3mf.

Yep, with this mechanism it will be possible for me to insert other illusions as well.

Step1: insert the cylinder into the center rod

Step2: screw the cap to the top

Step3: hold the cylinder with your fingers and lift the object to see the optical illusion in operation!
Step4: leave the cylinder and wait for it to return to the base

Step5: repeat and have fun!
