Gas Meter Box Key (Rectangular Type, Rounded Edges)

## 🇬🇧

### 🔑 **Polish Gas Meter Box Key (Rectangular Type, Rounded Edges)**

This is a **gas meter box key** commonly used in **Poland** for opening outdoor **gas enclosures** (*skrzynki gazowe*).
The key tip has a **rectangular profile**, **10 mm** wide at the top and **12.8 mm** at the base, with **rounded sides** for a smooth fit in the lock.

On this version, the **thickness of the key increases slightly from 7.2 mm to 8.2 mm**, forming a gentle **wedge (taper)**.
This helps it fit properly in Polish gas meter boxes, where keys with a uniform thickness sometimes don’t insert fully.
The wedge shape ensures a snug fit and easier operation.

This **rectangular style** is typical for many Polish gas meter boxes — it’s *not the same* as the **triangular utility keys** used in other European countries.

🧱 **Recommended materials:**
Print in **PETG or ABS** for durability.
**PLA** may be too weak or soften in heat.

💡 **Tip:**
For better grip and accuracy, print with **3–4 wal
