# Tacho mit LED Ring
Das Grundmodell ist von [alvaroalea auf Thingiverse](https://www.thingiverse.com/thing:2489322)
Erweitert wurde:
- Ziffernblatt 0 - 220 km/h
- Rückplatte mit Auslass für die Kabel des LED Rings [hier](back_with_hole.stl)
- Platte mit Vertiefung für LED Ring [hier](bezel_LED_Tacho.stl)
