Introducing my Original Boeing 737 Dual control roll channel design. This design was purely created with the size of the Ender 3 build plate in mind and the majority of the parts are printable including all the gears. The hardware such as bolts and bearings will still have to be purchased. This makes for a cheap, working dual controls system.
You can see this design in operation and the build on my YouTube channel. It works really well and now includes the modification to stop the yokes from turning past 90 degrees.
The tighter the gears, the less play in the system. I must personally admit, That I have no idea how long the plastic gear will last, but if they do finally wear, you will be able to reprint them.
This Design includes:
1) Dedicated STL files
2) The fusion 360 CAD design for editing.
I have already issued the metal framework plans for free and be found here:
These are designed around using 3mm thick, 38mm square stock steel.
The build/parts & print guide can be found here:
Kind Regards Karl & Helen.
YOU WILL NEED FUSION 360 OR CAD SOFTWARE TO EDIT AND CREATE CUSTOMISED 3D PRINT FILES FROM THE DESIGNS. YOU MAY NEED TO ADJUST THE DESIGN TO SUIT YOUR PVC PIPE SIZE AND SHAFT DIAMETERS.
