This is the first version of the EFIS that has spent several months testing with my Patreons. This version has gone through many tweaks in the hope this it will print perfectly on most machines that have been calibrated. 
 
The design has been split into smaller sections to make it easier to build and print. The gearing has been fine-tuned, and tolerances have been adapted to suit most people's builds over various printers.
 
The whole unit can be 3d printed, but our webshop offers laser-etched panels to improve the aesthetics.  The Laser DXF files are included.

This Design now includes Stefan's Mods to allow the use of D-shaft rotary switches and a larger box to house an internal Arduino.
