I designed this case in OpenScad to make a removable case for the Reprapdiscount LCD controller. This case contains a full encapsulated case (top and back), emergency stop button, a mounting bracket for 90-degree printers, and a lock-kit which locks the case to the mounting bracket.

Use your own reprapdiscount knob. The photo shows the following knob http://www.thingiverse.com/thing:172996

The back cover plate contains two nibs inside to prevent the lock from disengaging. The mounting bracket has been coded with mounting holes which match the back plate of the Hadron OrdBot printer. Feel free to drill your own holes to suit your own printer style.

The LCD controller can be installed in two ways:

• by mounting the lock plate directly onto the printer' vertical back support
• (optional) or by installing the printed risers onto the T-Slot extrusion, then install the lock plate onto the risers. The holes in the risers match with the lock plate.

More changes!

The SCAD file has been updated to include a RISER BRACKET to allow for adjustable height to elevate the LCD above the Z height of the X-axis on a 90degree style of printer.

Print the two new parts: Chris_lcd_riser-Right.stl and Chris_lcd_riser-Left.stl. Install them in the T-Slot of your printer with T-slot nuts. Attach the back plate bracket from of the LCD to this new riser. See the photos for more detail. I hope that you enjoy this LCD case.

Print the parts of this case in PLA with 20% infill at 0.2mm layer height.

Printing time:
Top case: ~ 3 hours
Back cover: ~ 2 hours
Mounting bracket: ~ 1 hour
Lock kit: ~ 24 minutes
Button: ~ 15 minutes
Left riser bracket: ~29 minutes
Right riser bracket: ~29 minutes

The OpenScad file has been included. The code is clearly segmented into modules, however it is highly recommended that you do not edit this file unless you are extremely proficient with OpenScad.

Assemble the case parts carefully. The emergency stop button is a precise fit inside.

The screws required are similar to 9gram RC servo screws or other 1/8" (2mm) with large flat heads. See the photo that displays all parts disassembled for reference.

The riser brackets require (2) T-slot nuts + (2) bolts to fit the t-slot nuts. Drill out the holes in the risers to accommodate your chosen hardware. Attach the back plate to the risers (optional) to raise the lcd above the x-axis Z height.

Slide the locking arm fully to the left or right to engage the lock in the case.

Be sure to print your own favourite reprapdiscount knob and install it onto the assembled case

I hope that you enjoy this case.
