3D-Reconstruction: Building a small, simple Turntable [Video]

22 September 2024

In this video we’re building a small and simple turntable that we can use to take photos of an object in regular intervals. By combining the turntable with gphoto2 most of the process happens automatically.


This is the second post in a series about 3D Reconstructions. The first post gave an overview of what we’re going to do and about the machine I built to automatically capture pictures. In this video we’re looking at one part of the machine, namely the turntable:

The turntable is only one part of the entire machine. In the next post we’ll either look at the remainder of the machine (there’s so much to say, I don’t really know where to start) or we’ll move on to an introduction to Meshroom.

    Excellent videos. The rotational resistance caused when tightening the upper bearing is simply because of a lack of endplay, due to the overtightened nut. Instead of the elegant, yet complicated multi-piece setup, why not simply use a threadlocking compound? Blue if you want to remove the nut again, red if you want it rather permanent. Just a thought

    1. Hey, thanks for the comment! You’re right, a thread-locking compound would make the design easier. I did look into it a little when I built the turntable. I didn’t go for it because I liked the idea of just doing it with screws and nuts (and it was fun to do it in this puzzle-like fashion), but maybe it’s worth revisiting the design to make actually make it ‘simple’ like the title suggests …
