Resistor Label Generator for 3D Printed Storage Box

This script generates resistor labels as images and compiles them into a printable PDF. It allows customization of label dimensions, fonts, page sizes, and resistor values. Currently it will generate a set of labels to fit my print profile found here

How to Use

This process is easiest if all steps are done in the terminal.

1. Install Python (if not installed)

   • Download and install Python from https://www.python.org/

2. Create a Directory for the Script

   mkdir -p ~/Downloads/resistor_labels
   cd ~/Downloads/resistor_labels

3. Download or Copy the Script

   • Save this script as resistor_labels.py inside the resistor_labels folder.

4. Set Up a Virtual Environment

   python3 -m venv venv

5. Activate the Virtual Environment

   source venv/bin/activate  # On macOS/Linux
   venv/Scripts/activate    # On Windows (Command Prompt) (may need to swap to backslashes)

6. Install Dependencies

   pip install Pillow reportlab

7. Ensure a Valid Font File is Available

   • The script requires a TrueType font file (TTF). If Arial.ttf is missing, either:
     • Place an Arial.ttf file in the script directory.
     • Change FONT_PATH in the script to another available font (e.g., /usr/share/fonts/truetype/dejavu/DejaVuSans-Bold.ttf).

8. Run the Script

   python resistor_labels.py

   • This will generate resistor label images in the labels/ folder and create labels.pdf containing all labels arranged for printing.

Customization

Modify the values in the script under each section to change label dimensions, page size, font, etc. """
