3D model
Model is build with OpenScad, permitting to create parametric models, this is really usefull for optimization and alternatives.
There are 4 main parts, this is monted as illustrated below
The module structure:
The rotor in 2 parts,
And the stator for the mounting elements :
And for card fix :
All Parts Printed result :
Electronic Card
Electronic card is composed of a leonardo microchip, this chip handle the motor, homing, and communication. And external USB connected unit gives the numbers to display.
A lonely electronic card is hosted in the display.
How to mount flip display
Step 1 : solder the switch,
Step 2 : Mount motor on stator :
Step 3 : Switch mounting
Put the stator into the mounted rotor and fix them on the support using the 2 skrews. Take caution of the cable there is calculated space to not make the cable be damaged.
The final result with no box:
