The ultimate printer I can recommend is the Bamboo Labs X1 carbon with AMS if you have deep pockets. ($1200). It's a massive leap forward in 3D printing, with excellent quality and impressive speeds. Its pretty much press print and go as the software and hardware do the calibration before each print. This printer will not manage the larger parts and you are going to need the CREALITY CR10 v3, which is my second choice of printer.
​

This product is fully designed to be 3D printed. It's a massive build (actual size) and my biggest 3D print yet, requiring a minimum print bed size of 300 x 300mm. It's sturdy and probably over-engineered, but I wanted that it that way as there can be a lot of force exerted through a person's legs onto the unit. It has a total of 3 axes:
1 x rudder axis
2 x brake axis
This can be easily achieved using an Arduino micro pro. I have included a lot of bearings to make the unit feel smooth and to help spread the load exerted between the parts. The pedals are not only supported by plastic but metal threaded rods to help share the loads.
The pedal position is fully adjustable forward and backwards by around 100mm. This is achieved by the adjustment handle at the front of the unit just like the actual aircraft.
Please note: This is a massive 3D print taking around 2 weeks to complete and 4 rolls of PLA. For more advanced users, building the footplates and centre tower from wood may be quicker.
