Summary
This is a derivative of the PanelMax Prusa - http://www.thingiverse.com/thing:21135 by TommyC. It adds a couple of small pots for LCD brightness and contrast, along with changing the size of the reset switch to small and low profile.
Quick video of it in action here:

The click encoder, pots and reset switch are mounted on a breadboard within the enclosure which has expanded to fit them.
As the name suggests it was primarily designed for Sanguinololu - it moves the SDSL card reader: www.reprap.org/wiki/SDSL from the ISP and top of the expansion header into the case and uses every other free pin on the expansion header.
Having recently built a Mendel 90: http://reprap.org/wiki/Mendel90 I am a convert to ribbon cables so this design uses a single 22 way ribbon cable from the expansion header+isp header to the enclosure. Obviously you can use a different connectors on the end to connect it like the PanelMax to RAMPS or other electronics.
Update - works with Printrboard, see: http://blog.think3dprint3d.com/2012/07/panelolu-with-printrboard.html for details

UPDATE #3 - I have re-uploaded the files after tweaking the hole sizes and the strain relief. I have printed over 20 of these now and feel its time to take off the "work in progress" status
UPDATE #2 - Mistake in commenting meant the previous update did not have the hole in the prusa lower mount clamp - scad and stls fixed now.
UPDATE - If you downloaded the panelolu.scad or panelolu front_left.stl, I have updated the files due to an error that had the letters reversed and a couple of other problems that are now fixed.
The firmware changes required to Marlin to make it work are documented on this blog post:

OpenSCAD file now available.
The knob is tommyc's adaptation of this: thingiverse.com/thing:17404

PrintBit's design for a MendelMax box is a nice mounting solution:
http://www.thingiverse.com/thing:44398http://www.thingiverse.com/thi...
WE are currently supplying the Panelolu2
http://www.thingiverse.com/thing:50709http://www.thingiverse.com/thi...
which does not yet have a similr mount for MendelMax but if you asked for it without the LCD attached t the circuit board you could adapt PrintBit's design.
I prefer to have the Panelolu/Panelolu2 unmounted so I can move it around.
Hi
Have just received one of your kits and am printing out the parts for left hand side fitting. I have noticed (bit late now as it is half way through printing) :( that the R B C letter on the front part are the wrong way round I assume due to the mirroring from the right hand ones. Thought it would save anyone else having this problem as they can fix it before printing.
Ken
The files are now updated - The other mirroring error will affect how well the breadboard mounts so I think you will have to print it again - so sorry!
No problem thats the reason for having a 3d printer to test stuff out :)
will let you know how it goes.
Hi Ken
Sorry I did check and change this - just checked the scad and it also has another error (the support for the screw to close the case below the click encoder does not mirror across). :-[
I will update the scad and stls now and upload them.
Detailed instructions now up:

Took almost as long as the design!
Excited to see your detailed instructions mate! So your enclosure holds the LCD, the click nob, the reset switch, britpghtness knob and contrast knob. You wire them up and run them to a ribbon cable socket. So, you could actually just as easily run this to a RAMPS board or whatever really, right?
Yes - LCD, buttons and knobs and the SDSL (so if you already have an SDSL you can use that already) The ribbon cable goes to an iDC connector that plugs over the iSP and expansion header on the Sanguinololu but no need to fit the IDC if you want to connect it up to RAMPS. The only thing is there need to be the right number of pins left from the ATmega to run the LCD, click encoder and SDSL.
