Material : PLA
Color : Any
Layer Height : 0.2mm
Infill : 15% (rectilinear)
Supports : None
Rafts : None
Print Time : ~12 Hr.
Note:
Clock_Face.stl :
Lower Layers must be printed with material that pass light if backlight is needed. Add 3 or more top solid infill for preventing the backlight penetrating through unwanted areas
Print in Two Colors. You can print multiple colors in single extrusion printer by filament change method. For that Use M600 Command After 3/4 Layers (for 0.2mm layers) in the GCODE .
In Prusaslicer you can add colors easily without messing up with GCODE and view the code graphically for more convenience.
Print a minute hand and an hour hand.
Place NodeMCU and Servos as shown in the images.
Flash NodeMCU with codes attached. (Some parameters has to be modified accordingly like your 'Time Zone', 'Wireless Credentials', 'Servo angle', etc. )
After completing and checking the connections, the back panel can be secured using six M3 screws. (careful while tight into plastic parts)
Done :)
