Boeing 737 Throttle Quadrant v3

This page is split into three main sections:

Parts Guide

Print Guide

Build Guide

These units can be produced on a standard 3D printer bed size of 220 x 220mm.

My 3D Printer of choice right now is the ENDER 3 v2

Great print & build quality for the price and Karl personally recommends it for his sim build.

General Information:

This 737 Throttle quadrant is the 3rd iteration for the 3d printed Sim community. This unit is much stronger, simpler and better than previous versions! It should also be much cheaper when an Ardunio Micro Pro/Leobodnar interface board at around 3-6 Euros instead of a Leo Bodnar Board costing 25 Euros. This has taken several weeks to perfect, and you can see the final result in my Youtube video.



The unit features:

Operational Speed Brake Lever

Dual independent Thrust Levers

Dual independent Thrust reverser levers utilising potentiometers

Flap lever with gated guards

Bell cut out switch

A/T Disenagage switches

TOGO switches

Operational detente Brake lever

Working Park Brake Light

Operational Fuel Cutoff Levers

Operational Stab Switches x 2

Friction Brakes on the main levers
