Boeing 737 AutoPilot Panel (MCP) for MSFS2020, Prosim & PMDG

This design is a remake of the $38 DIY MCP. It's a newer, better version, taking full advantage of 3D printing. This is not an exact replica, but it is fully functional. The design has been modified for larger text, so it's easier to print with good quality clear and crisp text. Various components have been moved to allow easy fitment. All parts assemble easily and require no additional mounting hardware besides their attachment nuts and screws. Also, full 7219 boards are used, so the wiring is much easier!
A massive Thank You to Sebi Woelke for the Intro and Logo!

Loving the work that you do. You've really been helping us build better and more affordable simulators and I must thank you for that. I have only entered the 3D printing work recently and I am eager to get started on this. I might try doing a modification to your design in the future and incorporate a painted/engraved perspex faceplate that can be backlit. But it really looks brilliant as it is

[@helimech8152]

Hello Damon, Love that you are already thinking ahead! As this was the basic version, I kept it simple. It is now just a matter of time to create more complex versions. But if others are willing to create the next version, thats awesome! Kind Regards Karl

Inspired from your videos, Im just done with my "38 EUR" MCP. Was also about one year in the making, but I'm still on FSX PMDG 737. I designed my front and base plate out off PCB's then ordered them in china. It saved me all the mechanical work and a lot of wiring cause I soldert all the components in it. I had my issues by setting mobiflight up, but now everything works just as I want to. (except I can not program the speed display in mach) Thank you for those great videos, i enjoy them everytime. Regards from Germany to Brunei

Are you using easyEDA by any chance? would be really interested in the PCB project.

[@a-em]

@@karlisk4 hallo, no for this I used eagle. And to be honest, I made some mistakes on the electrical design. But I could fix them with a few extra air wires. And don't daisy chain 5 led displays together, it won't work. I did split them in 3 now. The mechanical design however was a perfect fit 😀

No. It’s optional You can print it all on a 3D printer.

Thank you for all your effort. The only thing I haven't seen, that I think might help, is a rough estimate of how many KG of each colour I'd need for a model (unless I've missed it).
