Seeing it being built shows the simple genius in the design.

Hi woodwaker1,
I must admit I stared at the video for about half an hour before it dawned on me...

That is even more impressive, when you stand it on it's side 👍

[@popzct]

Yes, I thought I'd answer the magnet or not magnet sooner than later.

Thank you!

Enjoyed that a lot Greg. Vertical display is so cool. Should work with a totally flat background as well and would give a different effect. But you would have already tried that to get to this point in the build. Thank you for sharing with us.

[@popzct]

Thanks John, I'm truly glad you enjoyed it! On a side note, I showed our youngest grandson your Robothut channel and he loved it so much I bought him the same 3D printer you used, so thank you!

Amazing! Like some magic tricks, it's even more amazing when you know how it's done! Beautifully done!

Pretty neat. So now I wonder... if the balls were the magnets and the magnets shown here were a large washer with no magnet properties... I wonder if the grooves on the top would guide properly. Great build. Thanks for sharing.

[@popzct]

Thanks you! No it would not work as designed.
Greg

[@mpzr]

Amazing work Greg. It's time to fire up the printer

[@popzct]

Thank you, best wishes!

Impressive.

Thank you!

I'm wondering if one less tooth on the gear of the magnet spider, and one less arm on the spider might allow the circle of balls to rotate. This would be more easily seen if one (or more) of the balls were coloured.

[@popzct]

The "tracks" would have to be removed.
Greg

[@MicrobyteAlan]

Good one 👍

[@popzct]

Thank you MicrobyteAlan, I'm pleased your enjoyed it!

[@Gunnahan]

isnt it astounding how 2 rotating wheels can end up making a linear motion ;-)

[@popzct]

[@wasdaletimelapse7658]

Thank you so much for the reveal. I, like many others, are now looking through all my Lego components to see if it is possible to build. I shall get busy tomorrow to see what I can achieve. Thanks again for sharing.

[@popzct]

You are very, very welcome, and I'm glad you enjoyed it!

Hii i have a doubt in your 2 year prior 3D printed quick return mechanism and i have also read info of the project in the link you given below but in it their no size or dimension givenn kindlyy please help with that

[@popzct]

I'm truly sorry, but I do not understand your question. Do you have a link?
