### Simson Custom Key Fob 

This is a custom-designed, multi-color key handle/fob collection for Simson enthusiasts.

 It features a clean, professional finish with a dual-color design achieved through a simple filament change, making it printable on any single-extruder 3D printer!

 Available versions included in this project: **S90**. 

Just choose the file that matches your moped! #### 🛠️ Specifications & Print Settings: * **Material:** PLA or PETG (both work perfectly).

 * **Multi-color:** Designed with a filament change at **layer 39** (from black base to the colored text and accents). * **Surface Finish:** Top surface **Ironing** is enabled in the 3MF files to achieve a perfectly smooth, premium look.

 * **Included Files:** Standard STL files for each variation and pre-configured 3MF files optimized for various printers. 

#### 🔑 Key Installation Guide (Important!): The back of the model features a custom slot measuring **5mm x 2.1mm**.

 To secure your Simson key into the handle: 1. Hold the metal part of the key carefully with pliers. 2. Heat the end of the key shaft using a torch or lighter. 3. Carefully press the heated key into the plastic slot on the back of the model. The plastic will melt slightly around it, creating a rock-solid, permanent bond once cooled. Enjoy your upgrade, and happy printing!
