Marblevator, Self Reversing Screw Mechanism, Prototype 1, Three Ball Bearings

A video showing the use of three 11mm nylon ball bearings on this Marblevator because someone asked.
Advance warning: this is a high precision 3D printed, filed, sanded and polished mechanism.
As a side note, my wife and I have been busy building a living space for her parents in our home as they both are in the advanced stages of dementia and can no longer live by themselves. They are now in our home and my wife and I are spending a lot of time providing care for them, so for the time being, I will be publishing fewer videos.
Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.12.1, and 3D printed in PLA and Tough PLA on Ultimaker S5s and an Ultimaker 3e.

Hi, Grandpa ! Are you commenting on this video from your Coffee Shop ? - Robert. 🙂

@@Unknown15916 It takes me all my "coffee break" time to film the midday snack short, edit it, and upload it to UA-cam, Google Maps, Pinterest, Instagram, and Facebook. Especially when the coffee shop wifi is poor, it is often quicker to use my mobile data. 😁🎥📸✂⌛⏲

Where did you source your Nylon Balls from ?

[@popzct]

I purchased mine on Amazon.
