This model is a compact protective enclosure for an optical endstop sensor (OPTICAL ENDSTOP) used in many 3D printers, CNC machines, and other motion control systems.

Optical limit switches are often installed without any protection, leaving the electronic board exposed to dust, mechanical damage, or accidental contact. This housing helps solve that problem by enclosing the sensor board while keeping the optical detection slot open for proper operation.

The design allows the optical endstop module to fit securely inside the case while providing a simple mounting solution for custom machines and DIY projects. The enclosure also helps organize wiring and improves the overall appearance of the installation.

This model is ideal for makers who want a more durable and professional-looking installation for their optical limit sensors.

Features

✔ Protective housing for optical endstop modules
✔ Improves durability and protects electronics
✔ Keeps the optical detection path unobstructed
✔ Simple and compact design
✔ Easy to mount in DIY machines

Recommended Print Settings

The model was designed to be printed with ABS for improved strength and heat resistance.

Recommended settings:

• Material: ABS

• Infill: 100%

• Layer height: 0.2 mm

• Perimeters/Walls: 3–4

• Supports: Not required

• Brim: Optional (recommended for ABS)

Printing with 100% infill ensures the enclosure is strong and resistant to vibration when mounted on machines.

Recommended Print Orientation

Print the housing flat on its bottom surface.
This orientation provides the best strength and eliminates the need for supports.

Assembly

1. Place the optical endstop board inside the housing.

2. Align the optical sensor with the slot opening.

3. Route the cable through the opening in the case.

4. Mount the housing to your machine frame if required.

Typical Applications

This enclosure can be used in many maker projects:

• 3D printer limit switch protection

• CNC machine endstop mounting

• Laser engraver positioning systems

• Robotics projects

• DIY automation equipment
