Digital Microscope Andonstar ADSM301 to Microphone Arm Adaptor

I needed an adaptor for my Andonstar ADSM301 digital microscope to a microphone arm. I found a three-armed mic arm from Amazon (http://bit.ly/4dtOHLn) that did the job (any mic arm will do, though). The hole size for the microscope lens is 35.90mm in diameter, but could go up to 36-37mm.

I have designed four types with:

• No handles

• Left handle

• Right handle

• Both handles

Filament & 3D Printer Used

• I used eSun PETG black filament on a Flashforge Adventurer 5M 3D printer.

Supports:

• Only used supports for the control holder. I printed it flat end up.

Materials Needed

• Lid/Cover = two M3*8 self tapping screws

• Control Holder = two M3*8 self tapping screws

• Circuit Board = two M2*6 self tapping screws

• Clamp = one M3*12 bolt and nut

• Mic Arm = nut size around 17mm in diameter and 8mm thick. I bought a pack of 10mm bolts with nuts from a local DIY store.

Assembely

1. Start with the circuit board, and place it into the space for it. Now use the two M2*6 screws

2. Fit both LED lights into the holes on the opposite side of the circuit board (see photos) by screwing them in with a pair of pliers, and have the wires poking out the other side

3. Solder the wires onto the circuit board. Make sure black goes to negative (-) and the red goes to the possitive (+)

4. Fit the Lid/Cover over the wires and holes, and use two M3*8 screws

5. Place the nut into the hex hole as far as it can go. I used a bolt to help

6. Fit the control holder using the two M3*8 screws

7. Screw the base to the arm as far as it can go. You may find it easier if the LED lights are bent over (see photos)

8. Now, place the microscope into the hole and use the M3*12 bolt and nut to clamp it. Don't go too tight.

9. Plug everything in and enjoy!

Note:

After testing the adaptor, I have found that the control holder is slightly loose. In time, I will change it when I have time, but it does work.
