3D model description

But it was impossible for me to change it in a way to make it easily printable. So I decided to make my own version. But I wouldn't do it without using the excellent professional made little elastic kill button.
While I created this case I had neither the LDC board nor the LCD. So "Hardwarekiller" send me, very exactly, all the needed measurements by email - and everything's fit well.

3D printing settings

To let the case apear more flat (and to cover possible impressisions ;-) I created a channel outside between the top and bottom part.
I had to learn that the LCD sizes are a bit different even if they look similar. Therefore I made two variants of the top case with different cut outs for the display:
Top Case cut out 98.4 x 40.4 mm
Top Case cut out 97.4 x 40.4 mm
There are also two variants of the bottom case for the cable slots coming out only on the front side or on back and front side:
Bottom Case front slots
Bottom Case back and front slots
The case with back and front slots is 0.5 mm higher to give more room for the cable between the controller board and the bottom, in case you want the cable coming out on the back side.
The bottom part contains several screw nut deepenings for fastening the case as you like. If you mount it to an 8 mm rod you can use the case clamps.
If you use the kill button 8.5 mm it will stick out 0.5 mm. It is then easier to push.
To assembly you need:
4 screws M3 x 12 with nuts
4 screws M3 x 20with nuts
2 self-cutting screws 2 mm x 5 (for the button but it works also without tighten it).
To get the controller knob lower you have to shorten the tack for about 4 mm.

Edit 29.12.2012
"MikeP-NZ" post his printed controller case but use a different knob. I think it is much more practical to use this thinner knob. One can revolve it faster. So designed one like that and - I enjoy it already :-)

Update 03.May 2014
I add "controller knob 6,4"
It has an inner diameter of 6,4 mm which is 0,1 mm more.
