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.

<b>I have designed four types with:</b>

- No arms
- Left arm
- Right arm
- Both arms

<b>Filament & 3D Printer Used</b>

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

<b>Supports:</b>

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

<b>Materials Needed</b>

- 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.

<b>Assembely</b>

- Start with the circuit board, and place it into the space for it. Now use the two M2*6 screws
- 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
- Solder the wires onto the circuit board. Make sure black goes to negative (-) and the red goes to the possitive (+)
- Fit the Lid/Cover over the wires and holes, and use two M3*8 screws
- Place the nut into the hex hole as far as it can go. I used a bolt to help
- Fit the control holder using the two…
