Cessna Trim Wheel
This page is split into three main sections:
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.
A manual designed trim wheel for the Cessna. It utilises a single 10K ohm pot supported by 3 604ZZ bearings. A very simple build and the unit features a built-in indicator that is run from the trim wheel position. No servo is required. I would suggest connecting the single pot to an Arduino micro with the joystick sketch.
