C172 Fuel Select Panel (FSP) – CAD & STL Files
🛠️ Product Description
Bring authentic Cessna 172 ergonomics into your home cockpit with this highly detailed C172 Fuel Select Panel (FSP) digital download.
Designed with precision and realism in mind, this panel replicates the tactile feel of the real mechanism thanks to its carefully engineered lever system.
Karl devoted significant effort to ensuring the selector doesn’t feel like a simple 3D print — instead, it has a mechanical, weighted movement made possible by incorporating 6 mm ball bearings into the design. This small detail makes a big difference in realism and durability.
