ESP32 Breadboard Expander Spacer + Mounting Base

If you've ever dropped an ESP32 into a breadboard, you already know the struggle: most of the pins get blocked, and you lose precious holes on both sides. Why? Because breadboards were invented decades before dev boards got thicc.

This print fixes that.

🔌 Spacer: Sits between two breadboards, allowing you to mount an ESP32 (or similar-sized board) without blocking pin holes.

🧱 Base Frame: Holds both breadboards in a solid enclosure — keeps everything aligned and looking sharp.
