Tiny Snap-Fit Arduino Micro Pro Case Compact

I needed a super small enclosure for a simple Arduino Micro Pro project that only needed a single switch. This is what I came up with!

This tiny case is designed specifically around the Arduino Micro Pro, a single mechanical keyboard switch, and a 3mm LED (or small NeoPixel). Everything fits snug with tight tolerances and no hardware required.

• Ultra-compact footprint
• Fully snap-fit design (no screws)
• Easy to Super Glue for a permanent solution 
• Designed for 1x mechanical keyboard switch
• Fits 3mm LED perfectly (recommended for easiest install)
• Can also fit a small NeoPixel and 5 mm LEDs (but it's tight!
• Rotatable end caps:
  • One orientation = wire cutout
  • Flip it = solid face for logo/label

The enclosure is ideal for:

• Macro pads
• Custom hotkeys
• Tiny HID devices
• Desk gadgets
• Arduino-based micro projects

The snap-fit tolerances are tight for a clean finish, so print accuracy matters. A well-tuned printer is recommended.

If you need a small, clean, modular enclosure for your next Micro Pro project, this works great!
