Enclosures for electronics in 3D Printing - Mini Project: Build & Apply

Enclosures for Electronics

📖 Scenario: You have a small electronic device that needs protection from dust, moisture, and accidental damage. You want to create a custom enclosure using 3D printing to keep the electronics safe and organized.

🎯 Goal: Build a simple 3D printable enclosure design for your electronic device by defining its dimensions, adding ventilation holes, and including mounting points.

📋 What You'll Learn

Define the enclosure dimensions as length, width, and height.

Set a wall thickness for the enclosure.

Add ventilation holes on the sides.

Include mounting holes on the base.

💡 Why This Matters

🌍 Real World

Custom enclosures protect electronics from damage and environmental factors while allowing airflow and mounting.

💼 Career

Designing enclosures is important for product designers, hardware engineers, and makers who create reliable electronic devices.

1

Define enclosure dimensions

Create three variables called length, width, and height with values 100, 60, and 40 respectively to represent the enclosure size in millimeters.

3D Printing

# Define enclosure dimensions
# Your code here

Need a hint?

Use simple variable assignments like length = 100.

2

Set wall thickness

Create a variable called wall_thickness and set it to 3 to specify the thickness of the enclosure walls in millimeters.

3D Printing

length = 100
width = 60
height = 40
# Set wall thickness
# Your code here

Need a hint?

Wall thickness is usually a small number like 3 mm for strength.

3

Add ventilation holes

Create a list called vent_holes containing three tuples representing the (x, y) positions of ventilation holes on the enclosure side: (20, 10), (50, 10), and (80, 10).

3D Printing

length = 100
width = 60
height = 40
wall_thickness = 3
# Add ventilation holes positions
# Your code here

Need a hint?

Use a list of tuples to store hole positions like [(x1, y1), (x2, y2), (x3, y3)].

4

Include mounting holes

Create a list called mounting_holes with two tuples for mounting hole positions at (10, 50) and (90, 50) on the enclosure base.

3D Printing

length = 100
width = 60
height = 40
wall_thickness = 3
vent_holes = [(20, 10), (50, 10), (80, 10)]
# Add mounting holes positions
# Your code here

Need a hint?

Mounting holes help fix the enclosure in place. Use a list of tuples for positions.
