DIY Bluetooth Spinning Music Stand

Have you ever wanted a display stand that does more than just spin? In this project, I’ll show you how I built a DIY spinning stand that plays music via Bluetooth. It works as both a rotating display and a Bluetooth speaker, so you can showcase objects while enjoying your favorite songs.

This build is simple, fun, and great for anyone interested in combining electronics with a creative project. Whether you want it for a desk decoration, a product display, or just a cool conversation piece.

This spinning music stand is a unique way to bring motion and sound together at Instructables 20th birthday!

This project includes:

Electronics:

1. Bluetooth audio module
2. Motor (for rotation)
3. Power supply/battery pack
4. Basic wiring + switch
5. Potenciometer

Build materials:

1. MDF wood (for the base + structure)
2. Screws/glue for assembly
3. Scroll Saw + Oscillating spindle sander

3D Printing:

1. Any CAD of your choice (I used Fusion 360)
2. Orca-Flashforge software
3. USB drive compatible with Adventurer 5 Pro (FAT32)

The project is built from two main systems that run together at the same time.

The whole system is powered by Batteries

Power is split into two branches:

1. One branch goes to the Bluetooth audio system (module + speaker).
2. The other branch goes to the motor drive system.

Bluetooth Audio System

1. Battery → Switch → Bluetooth Module
2. The Bluetooth module outputs audio to the speaker
3. Turning this switch on powers both the Bluetooth receiver and the speaker at once.

Motor Drive System

1. Battery → Potentiometer & Bluetooth Module → DC Motor
2. The switch controls whether the motor is on or off.
3. The potentiometer adjusts the voltage going to the motor, which lets you control the speed at which the motor spins.

Interaction Between Systems

1. Because they share the same power source and switch, turning on the speaker system will also turn on the motor
2. This means that when audio is playing, the stand can rotate at the same time.

This step will guide you through cutting and preparing all the pieces required to assemble the frame for the project.

1. To start, I transferred my measurements onto MDF and carefully cut out each piece using a scroll saw. Once the rough shapes were ready, I refined them with an oscillating spindle sander to get clean, precise edges. I also prepared two circular base pieces, which serve as the foundation for gluing all the smaller components onto later on.
2. Make sure to create 3–4 larger blocks in total. Two of these should be sized to hold the speakers securely, and another should be reserved for the switch. These don’t need to be huge, just larger than the thinner blocks that form the ring around the base. I decided to make 20 small pieces in total. These pieces are skinny and are meant to be glued to the circular base.
3. When drilling the holes for the speakers, measure the speaker’s radius to determine the area to drill so the right portion of the speaker is visible and sits correctly.
4. Cut three equal-sized MDF pieces and drill a snug circular hole in the center. This will later be used to hold the motor head upright so the top stand can spin smoothly. Ensure the motor mount wood pieces are slightly shorter than the smaller blocks so the stand stays level and doesn’t rise too high when everything is assembled.

These steps cover how I designed the mount that attaches to the motor’s spinning shaft that will eventually get glued to the circular wood piece that was made above. The height of this whole design will be determined by the difference in height between the smaller glued-on blocks and the motor mount pieces. This step is important because keeping the motor mount pieces shorter in height ensures that the spinning circular base will stay close to the blocks, making the design both more stable and more aesthetically pleasing.

Create the Base Disk

1. Draw a circle for the base diameter
2. Use Extrude to give it thickness

Create the Central Stem

1. Draw a smaller circle at the center
2. Use Extrude upward to make the stem

Create the Smooth Transition

1. Apply a Fillet to round it into a smooth curve.
2. Adjust the radius until it flows nicely

Add the Hole/Slot at the Top

1. When creating the hole, it’s important to match the exact dimensions of the motor’s spinning shaft. This ensures that once the part is printed, it fits snugly and spins smoothly without any wobble.
2. Create a sketch on the top face of the stem.
3. Draw a rectangle and then a circle make sure to plug in the measurements of the motors spinning shaft.
4. Use Extrude Cut to remove the unwanted material and shape the hole so it fits precisely onto the motor’s spinning shaft.

Once your design is finished, you need to save the file. I will take you through the step-by-step process of how to save the file properly to your desktop and how to eventually format it to be able to be 3D printed. This can also work for any design that you would like to 3D print.

1. On Fusion 360, click File and export. This will open a window where you can name the file, the type of file you want to export, and the location where this file will be saved. For file type, I used 3MF, but STL also works. Make sure to save it to your desktop for convenience.
2. Right-click on the file that will be on your desktop and in the 'Open with' section, select 'Orca-Flashforge'.
3. Once Orca-Flashforge has opened up, in the top right of the window, click 'Slice plate'. Once it is done slicing, click on print plate, and then once it's done slicing, select 'Export G-Code file'. Make sure to save this file to your desktop.

This is the file that you will 3D print

These are the final steps to transfer the file to the 3D printer and bring your project from Fusion to real life.

1. Plug in a USB drive compatible with Adventurer 5 Pro (must be FAT32) into your computer.
2. Drag the G-code file that you have saved on your desktop to the USB. To do this, go to Finder and find the location of the USB. Drag the G-code file into the USB, and make sure the file is fully copied before removing it from your laptop.
3. Turn on the Adventurer 5 Pro 3D printer and plug in the USB.
4. Go to the printing menu (2nd option down from the top) and select the USB option.
5. Find your file and select it. Click the green button to copy the file over to the 3D printer, and then it will start the printing process.

The 3D printer will heat up and then start printing. It took me around 1 hour to finish the print, but the exact amount of time for the design to print will be displayed on the printer screen. Once it is finished, remove it carefully.

You should now have the circuit complete, all the MDF wood material prepared, and the 3D printed part.

1. In my design, I used 20 small pieces along with 4 larger blocks. I placed one large block for every five small blocks, which gave the stand a more balanced and aesthetic look. I also positioned the speakers on opposite sides so the sound could project both forward and backward at the same time.
2. To mount the speakers, take two of the large blocks. Place your speaker on top of the blocks to mark where the screw holes should go. Once you’ve marked the spots, drill four holes in total — aligned with the speaker’s mounting holes. Screw in the screws to ensure that the speakers don't move anymore and are in a fixed position.
3. Use a hot glue gun (or another strong adhesive) to attach the MDF pieces securely to the circular base at the bottom.
4. Find the center point of the circular base and place the rotating motor shaft in the center, place the motor mount wood pieces accordingly to assure the rotating motor shaft is centered. Once you have this center point, glue the motor mount pieces to the circular base to secure this position.
5. Adjust the potentiometer to ensure that the voltage coming through is not too high. To know this, play around with it until the rotating motor shaft spins slowly.
6. Glue the 3D printed piece to the remaining circle piece, making sure to glue it in the middle.
7. Place the 3D printed piece onto the rotating motor shaft; it should fit snugly and not wiggle a lot.

Turn on the circuit and enjoy watching your toys spin while listening to your favorite music!

Happy Birthday, Instructables!!
