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.
The Korry 318 v4 SMD PCB is the newest, most refined Korry solution designed for the Next‑Gen 737DIYSIM Overhead and future panel systems. Built on a professional dual‑sided PCB with all SMD components pre‑fitted, it delivers exceptional reliability, clean illumination, and a compact footprint that fits perfectly inside the new Korry case. With white SMD LEDs for true aircraft‑style colour via the lens and dual ALPS tactile switches for a crisp, authentic click, the v4 sets a new standard in realism and ease of installation.
Available in Common Anode (2×3) and Common Cathode (2×2) variants, each unit is fully 5V‑ready and uses robust dual‑row Dupont headers for secure, hassle‑free wiring—whether you’re using shift registers, the BOB, or direct Arduino input. Supporting Caption‑Only, Press‑to‑Test, and full button‑input configurations, the Korry 318 v4 is the definitive drop‑in solution for modern, consistent, and professional‑grade simulator builds.
