This is an enclosre box designed from scratch for the Arduino UNO and the LCD keypad shield.
After some tries, the final design fits nicely.
-Redrill using a 3mm drill the two holes of the bottom.STL part for removing the self contained support layers.
Clean and trim parts if needed (for my printer all parts fits perfect).
-Use 2 pcs of M3x30mm bolts for holding the PCBs and closing the case (use these bolts for pre-threading the holes before assembling).
-Source files has been also included.
Multi color printing with single head:
The case logo is 1mm deep, so you can play with this data and your layer height for changing the filament color at the appropriate height.
On my setup: My first layer height is 0.4mm and the rest 0.25mm.
-I start printing the first color for 3 layers (0.4+0.25+0.25=0.9mm).
-Stopped the print at 0.91mm and change to the second color.
-Print 3 more layers (0.9+0.25+0.25+0.25=1.65mm).
-Stopped the print again at 1.66mm and return to the first color.
-Feb/28/2017 Added multi color layers info.
