Build Guide
The ultimate printer I can recommend is the Bambu Labs X1 carbon with AMS or P1P if you have deep pockets. ($1200). It's a massive leap forward in 3D printing, with excellent quality and impressive speeds. It's pretty much press print and go as the software and hardware do the calibration before each print.

This panel was designed by an Ex-Apache Engineer for fans and pilots of DCS Apache. It has been highly requested and can be 3D printed, including the faceplate. However, those who desire operational backlighting and high-quality, laser-etched panels can purchase them from the webshop. The panel features two operational throttle levers with detent operation, two trigger release mechanisms to prevent accidental operation/shutdown, a working friction lever, an APU push Korry indicator with a protection flap, a working Master power knob (no key), and a throttle sensor position located using two high-quality hall sensors for accurate positioning without dead zones. The panel is designed for desktop operation and can be printed on an Ender 3-size print bed of 220 x 220mm.
