This one is for J-version with TTL -external triggering (FW -110 or newer) and PC connectors.

The kit's mother/display board connectors are recycled for those extra connectors so unit is like 1/2 cm slimmer than standard one (see the picture).

You'll probably need to flip TextF & Top STLs upside down.
Having two colors:
-save TextF gcode
-add Top on the slicer's build plate
-align Top exactly with the TextF (take under the buildplate view)
-remove the TextF
-set Z-hop 1mm
-save Top gcode

Printing:
-load text color filament
-print buttons
-clear the build plate
-print TextF.gcode (the txt color)
-switch the filamnent to case color
-print Top.gcode
-clear the build plate
-print Bottom one
