Summary

This is my from-scratch copy of the "Straight Pole + Curved Hole Illusion" as shown on the Make Anything YouTube channel here: https://youtu.be/Gm-lCSPBdp4

I'm not completely happy with this design, it isn't as good as the original. I had some trouble with the gear and I didn't take the time to put detail into the card. But it works!

I made the stick square so that it would be easier to print.

Post-Printing

Assembly

Print one copy of everything except for the bearing, which needs three copies. Assembly is straight-forward. Insert the bearings into the bore and then slide the crank shaft in, passing through the gear. On my printer the fit is quite snug, so no glue is needed. Place the rotating platform on top and insert the pole and card. Again these were snug for me and didn't require any glue. Put the handle on the end of the crank.

Turn the crank and be amazed!

You know that make anything is selling this (printed) on his web store for $35

I just wanted to tell this, because alot of creators wouldn't allow this.

Thanks for the heads up, but this design is actually a "copy" of the Make Anything version. I watched the youtube video and was inspired to create my own version (from scratch).

To print the Pole Flat, what angle should it be tilted by?

I don't understand the question. You should be able to print it with one of the long flag surfaces down. Two of the sides would work for that and two won't because of the angle of the bottom connection.

When I import the stl in Makerbot, the pole is standing on the side which connects the pole with the rotating_platform. To make it flat, I have to change its orientation by rotating it. What would be this angle of rotation?

Find a "place surface on bed" function like they have in Simplify3d and then just pick one of the sides.

0:30 wouldn't the official name be "hyperboloid"? Cheers!
