A simple yet practical case, specifically designed for the low-cost servo testers commonly found online.
 

If you've used modules like these, you've probably noticed that they usually only come with a thin plastic casing

✅ Compact and lightweight design
 

✅ The operating knobs are within easy reach.
 

✅ Clearly mark the direction of the cables
 

✅ The input and output interfaces are equipped with printed labels.
 

✅ Universal cover design
 

✅ Two installation solutions are included
 

🔩 Two shell versions 🔩 Two shell versions 🔩 Two shell versions
 

There are two shell styles available:
 

Version One - M3 Hot Melt Inserts
 

Suitable for users who pursue more durable assembly.
 

Its installation holes are compatible withM3 Heat-fused InsertsThis allows the shell to be opened and closed repeatedly without causing plastic aging and wear.
 

Version 2 - Secure with M3 screws directly
 

Adopting a more compact structure, the installation hole size is smaller.

General Cover
 

The same cover is suitable for two shell versions, making printing and assembly much more convenient. 👍
 

🏷️ Built-in logos
 

Both the shell and the top cover are printed with the following logos:
 

🔌 Input terminal
 

🔌 Output terminal
 

➡️ Cable routing
 

These indicators greatly simplify the wiring operation during the installation process.
 

⚠️ However, before powering on the device, please make sure that the connection is correct once again.
 

Although most of the common servo testers I've tested use the same interface layout, different manufacturers occasionally use different wiring methods.
 

🤖 It's very suitable for DIY electronic projects.
 

These low-cost servo testers are used for much more than just testing servo motors.
 

As long as it's needed to be fast and adjustable.PWM signal sourceAll of them can be put to good use, including:
 

• ESC Test
   

• Brushless Motor Control
   

• Remote Control Experiment
   

• DIY Robot Development
   

• Actuator Testing
   

• Fan and Propulsion System Project
   

• General Electronic Prototyping
   

The large operation knobs support extremely fine adjustments, making them particularly useful in calibration scenarios where even the slightest signal changes are critical.
 

💡 Why I designed this product
 

This project actually originated from the inspiration I gained while working on another project. 😄
 

At that time, I was developing a prototype of an electric fan and urgently needed a stable way to fix the servo tester so that it wouldn't slide around when adjusting the motor speed.
 

One day, I suddenly realized that the spinning fan blades and the loose servo tester were definitely not the kind of combination I wanted it to be close to my fingers... 😂
 

Therefore, rather than relying on the fragile shell we originally had, I decided to design a comprehensive installation plan instead.
 

The final result is a simple and practical enclosure that turns the inexpensive servo tester into a truly delightful component in real-world projects. 🚀
