 If you want to make videos like this, you will need rotating display stand. The cheapest usable one you can buy is around 20 bucks, but almost all of them have predefined speeds and use the external power supply. Instead, if you have a 3D printer, you can make one. This is the rotating display stand that I made. I needed a simple and fast solution, so for now I just made a basic one where you can control the speed in both directions. In one of my next videos, I will update it to be controllable by external controller, for example a PC, which will allow me to precisely control the speed, angle, acceleration and position. I tested and it turns out it can easily rotate weights up to 3 kg and since it's using standard 9V battery, you can use it anywhere without the need of external power supply. Speed of rotation can be controlled up to 2 rotations per minute in 100 steps. To make this rotating display stand, you will need these few things. I used this KYK Japanese made taper roller bearing, but as you can see it's a bit wobbly. There might be a more suitable bearing for this case, but this is the only one that I could find. If you have any idea of how to fix this wobbling, feel free to write a comment and I will see what I can do when I update this device with the features I mentioned. There are only 4 parts to print on a 3D printer, base, top, gear and a knob. There is a link where to get them in the video description. This is how to connect everything. You can get the code from the link in the video description. Here is how is everything put together. To get more professional look I got a 3mm glass sheet and I cut out a disc with diameter of 40 cm. You can paint the bottom of the glass black as I did, but I later found out that in most cases you don't need to do that. I hope you find this project useful and I earned your subscription. Feel free to like the video and check my other projects. Thank you for watching.
