3D Printed Gravitrax Marble Lift

Here is my Gravitrax compatible motorized marble lift. I have designed it around a small 5V geared motor. It is designed to be easy to print and easy to build. Several variants can be printed to lift marbles to different height. The lift has 3 inputs and outputs.

Wonderful.....I've been hoping someone would make one of these and now it's here! Thanks so much! I know three little boys who are going to go crazy when they see it!

Damn, bought a gravitrax starter skit for my daughters birthday to find out that I have to buy a 3d printer :D:D:D:D Cool work !!

Hi ! Great lift !!!! Do you need to glue the motor hub to the spiral ? I printed the 40 80 120 one, and the spiral balances a bit too much when pushed away by the marbles on the last floor. Any idea to fix this ? Congrats again :)

[@RelaxiPlay]

I printed it, but the motor hub spins inside the spiral. What is supposed to create friction between the hub and the spiral? Thanks.

Bravo good project

Hi, can you make one witch is around 20cm high?

[@VolFX]

how do you feed the motor please

[@ethanferret7131]

You feed the motor electricity. That or human flesh, I’m not familiar with this species.

[@robloughrey]

What mm ball bearings are you using?

[@mr.berlingo8211]

Standard Gravitrax balls are ½” diameter

Thanks

I think the official product needs no battery cuz it’s manual

[@sofreshandcleanca]

Was able to successfully print this out. Worked really well: kzbin.info/www/bejne/eqHShoCbp99sbrs Great job! I used a battery pack with a switch on it to simplify and make a bit more portable. Would love an even taller one that would have the same height from each of the 3 pillars.

[@skeetarus]

This would be great with a section for a battery holder on the side. I might try remixing it for that.

Cool 👍👍👍👍, ich nutze auch 3D gedruckte Modele in meinen Kugelbahnen, zum Beispiel auch hier kzbin.info/www/bejne/h6mWl4WPpMh4d68

[@dinhtuan752]

Thanks for the example
