The ultimate printer I can recommend is the Bambu Labs X1 carbon with AMS or P1P if you have deep pockets. ($1200). It's a massive leap forward in 3D printing, with excellent quality and impressive speeds. It's pretty much press print and go as the software and hardware do the calibration before each print.
This design came about when Karl took the controls of his own sim pit. Fully functional EFIS panels are expensive, and Karl needed the full operational capability offered by Prosims functionality. This set him out on a mission not only to create a fully operational unit to upgrade his original design but create a unit that can be 3d printed and assembled by anyone at a push of a button.
This design is based around the Liteflow laser etched panel by www.cockpitsimparts.co.uk. This means if you purchase their Efis faceplate, it should fit directly on this working design. This will enable all parts to be backlit.
If you want to print the parts and keep them really cheap, it can still be backlit by printing the faceplate in white PLA, spraying grey and removing the paint with sandpaper on the raised text. It's not going to produce pristine results, but it's going to work.
On the other hand, you can print in PLA grey and use a white paint pen on the raised text for a good finish.
This unit offers all knobs with working pushbuttons—rotary switches and encoders.
This design requires a print size of 220mm x 220mm.
