Hi Karl,
I downloaded your 757/767 3D Printed Throttle (Order No. 12395) and have printed all the parts successfully.
Your design is excellent, and I congratulate you!
I had a couple of issues:
(1) The .stl files I downloaded for the Annunciators: SPAR VALVE, ENG VALVE and REV ISLN appear like this:

The letters are printed as depressions below the surface. However, in your Build Video, it appears that you are using prints in which the letters are raised above the surface. The process you demonstrate, of sanding the painted surface to expose the translucent plastic, is also possible only if the letters are raised.
Could you please clarify. If necessary, could you please upload the correct .stl files (or email them to me) so that I could print the version with raised letters.
(2) There appear to be some missing steps in the Build Guide. It jumps from Step 9 to Step 12 and from Step 35 to Step 37. Would you be able to provide the missing steps (if indeed there are any)?
Once again, I'm really impressed by your creative genius. I am following your progress on your design for the Motorized 737 Throttle Quadrant, and look forward to downloading it when it is ready.
Thanks,
Chakko.
