(updated)
Printable gamepad written in Openscad for the N900 similar to the Game-Gripper. You can grab the code or view a screenshot of the latest 3D model downthread. This is the initial release, fIrst print is done and issues needing fixes are noted below. This first release is sized for N900s with the Mugen extended battery cover. I will measure for regular battery once this prints and is verified, probably tomorrow.
The V0.6 design needs a few tweaks like resized non-jam buttons, moved or removed USB port, tiny tweaks of two button peg holes, move the joining screw holes and enlarge.

Please post requests while I am still working directly on the project and you will have a better chance of getting a .stl model file made. I have only used the Nintendo64 emulator for Mario64 using the accelerometer for direction input, so advice from emulator power users would be appreciated. I am also open to other 3D project requests depending on available time and difficulty.

Now also featured on Thingiverse! http://www.thingiverse.com/thing:113285 You can grab the ready to print .stl files there.\

I don't see any N900 game grippers for sale anymore, it appears that Game Gripper still lists them but they have been on backorder and this is absolutely the only way double-Scud and Mugen battery users can get a working gamepad. This is not a game gripper but rather a clean slate printable model.

Ideally the available models would include source code, I chose openscad, so that it becomes easy to modify. As a fun gimmick maybe put the gcode for the current release into an app that can control a Mendel Prusa 3D printer via host mode so the new open-griper releases would appear on the repos, or perhaps a packaged native version of http://www.openscad.org/

So the N900 gripper still looks to still be available from game gripper.
It seems it is still offered but is on eternal backorder. "Notify me when the stock has been refilled"
http://www.game-gripper.eu/buy_n900.aspx
Still even if is someday available again from game gripper, is there any interest in an open hackable 3D printable design being available? I had been playing Mario64 a while back but now the effort would mostly be for the community.
Also looking for cool upgrade ideas to implement. This is not aimed at making a pirate copy of the game gripper but rather to make something better and open/hackable.

How many TMO users do have access to a 3D printer and want to print N900 accessories?

in addition to this open gamepad you can print a replacement stylus
http://www.thingiverse.com/thing:21911
and two car mounts

I don't have access to a 3D printer, but these features would be great.

More button holes but with flat non-functional fillers that could be placed in unwanted slots.

One specifically for use with the N900 OtterBox case maybe with clips to lock it into the speaker holes, and if it's that big it could also use the camera and volume buttons for L/R or something.

DA5, once I get the gripper made you could send me pix and measurements for the Otterbox and I can see about modeling, I unfortunately don't have the skills to mod the camera and volume buttons in software though.

This is the prototype shell, I will code up some buttons and the control pad.

(Contains Obsolete/Incorrect Code)
Directional pad, the pegs reverse taper so should snap in and stay.
Code:
//button and control pad for open-gripper
//Controller cross cutout and pivot bump
	difference()
		{
		union()
			{
				translate([28,5.5,29])
					{
						cube ([8,22,4]);
					}
				translate([20,12.5,29])
					{
						cube ([23,8,4]);
					}
				//button hole at W button
			   translate([31.5,24,25])
			    {
			    cylinder(r1=2, r2=1.5,h=8);
			    }	
				//button hole at D button
			   translate([39,17,25])
   				 {
   			 cylinder(r1=2, r2=1.5,h=8);
			    }	
				//button hole at A button
			   translate([24,17,25])
			    {
			    cylinder(r1=2, r2=1.5,h=8);
			    }	
				//button hole at W button
			   translate([31.5,10,25])
			    {
			    cylinder(r1=2, r2=1.5,h=8);
			    }
			}
		//Pivot Bump
		translate([31.5,17,28.5])
			{
				cylinder(r1=3.5, r2=1.2, h=1.5);
			}
		}
and the buttons
Code:
//buttons for open-gripper
 
    cylinder(r1=1.5, r2=2,h=8);
    cylinder(r=4,h=4);

I don't have time to print this for a few days butif anyone wants to comment please do, You can help, especially with verifying measurements or improving layout.
improvements under consideration: ( Strikeout = Done)
-print a single layer mask with button holes to verify correct button placement(save print feedstock)
-making the through holes slightly cone shaped to match the tapered pusher pegs on the buttons.
-splitting the gripper into two pieces and connecting with screws to make slicing and 3D printing easier
-removing plastic from the area below the keyboard
-thinning the plastic holding against the battery cover
-rounding edges
-improve ergonomics
-make second version sized for standard N900 without Mugen extended battery covers
-redesign buttons and d-pad as two parts, the button side and pegs inserted from the back into holes on the buttons
-If gripper shell is split into two pieces use stainless allen screws facing forward to look extra cool.
-respond and include feedback or contributed code
-shrink buttons and dpad by 0.2mm on edges so they don't stick
