Summary

A simple case for the RepRapDiscount SmartLCD controller on a Kossel Mini with 15mm extrusions. It features an SD card slot and an emergency halt button.

Note: The knob for the rotary encoder is not part of this thing. I've used http://www.thingiverse.com/thing:6194

Instructions

Slice model and print case and button separately. I used Slic3r with 0.2mm layer thickness and a 0.5mm J-Head nozzle. Printing a few buttons at the same time improves their quality due to a longer cooling time between layers.
Use wire cutter, knife and file to clean out the SD card slot support structure.
Use 2mm drill to clean mounting holes on button.
Mount button inside of case with 2x small screws. The button should move freely inside of its hole and return to its initial position on its own.
Use 4x M3x8mm screws, washers and nuts to mount case in front of your Kossel Mini.
Insert SmartLCD controller board into case.
Use 4x M3x6mm screws to mount board inside of case.
Connect controller board with data cables.
Attach knob on rotary encoder.
Have fun with your controller case. ;-)

Note: Using a different color for button and knob looks more fancy ;-)
