About this 3D model

Welcome to one of the most advanced and ambitious 3D‑printable 737 throttle projects ever created. This unit represents nearly a year of development, testing, refining and re‑engineering, pushing every bit of design and simulation knowledge to the limit. Originally created for my own cockpit, this throttle has now been proven to work beautifully with ProSim 737, and thoroughly tested by the community with PMDG and P3D. Patreons can now buy dedicated PCBs for this unit on our Discord. This listing contains STL files ONLY, perfect for builders who simply want to print, assemble, and fly. But please be aware these were created in 206 for the older generation of #D printers, such as the Ender 3, which had much larger print tolerances. You may consider buying the CAD to adjust as required: https://cults3d.com/:3938725 A huge thank‑you to my Patreon community, whose feedback, test builds, and many rolls of PLA helped shape this into the robust, realistic, sim‑worthy unit it is today. Key Features This STL‑only version offers the full physical capability of the original design: Realistic, Functional Controls Motorised automatic throttles – can be safely overridden without damaging the stepper motors Automatic speed brake Thrust reversers with Idle / 80% / Max detents TOGA, A/T disconnect, horn cutout & stabilizer trim cutout switches Flap lever with all detents + “raise inadvertent” guard Fully working trim wheels (currently slow but fully functional) Mechanical & Print Quality Enhancements The steppers act as dampers, giving realistic resistance even with the power off Geared Hall sensors + potentiometers ensure full travel and accuracy Backlighting‑capable components for enhanced realism Interior case design keeps wiring organised and maintenance simple Printed parts achieve a rigid and sturdy feel, rivalling commercial throttle units What’s Included All STL files required to print the complete throttle unit Filament STLs Resin STLs Optimised for printers with a 300 × 300 mm bed Designed for straightforward slicing and reliable printing Smaller print mod available here: https://cults3d.com/:3938581 CAD files are NOT included in this version. If you want editable source files, please see the full CAD release. https://cults3d.com/:3938725 Requirements 3D Printer Minimum bed size: 300 × 300 mm If using a smaller printer (220 × 220 mm), you will need the Split‑Part Mod: ? https://cults3d.com/:3938581 Software Compatibility Supported: ProSim 737 Community‑verified: PMDG (MSFS/P3D) Not officially supported by me, but tested successfully by many builders. Important Notes Personal use only. YOU MAY NOT PRINT & SELL complete throttles or printed parts. Electronics and firmware are not included Build difficulty is advanced, especially on the electronics side This design works exceptionally well, even unpowered, due to natural damping Build Documentation Complete guides, wiring info, and build steps can be found here: ? https://www.737diysim.com/build-guides-1 Tip: Start with Build Guide 1 and continue to Guide 5 in order. Why Choose This Version? This STL‑only version is ideal if you: Want a complete print‑and‑build package with no need for CAD editing Prefer ready‑to‑slice files optimised for real‑world 3D printers Want the most realistic 737 throttle available for home use Are building a DIY cockpit on a budget while still demanding quality This is a deeply rewarding project, whether motorised or manual. FAQs Q: Does this include any CAD files? A: No. This listing provides STLs only. Q: Can I build this without ProSim? A: Yes! A PMDG build guide has been published and is widely tested. Q: Can I sell printed parts or assembled throttles? A: No—strictly personal use only. Q: Why are the trim wheels slow? A: They operate correctly but are being refined for higher speed in future updates.
