This is just a simple single digit rotary counter for table top gaming. I made it mostly with Munchkin in mind since after a few games/drinks d10's get unreliable. It's the first thing I CADded with printing in mind so naturally skeinforge complains a bit but it still printed well. I had to make it thicker than I originally intended since the local hardware store didn't have 1/4 inch screws. I'm using 1/2 inch since they're the shortest I could get locally.Update 3/2/12 I’ve added v3 of the pieces. These have fixed geometry.Use a number 4 (SAE) sheet metal screw to put it together. This should be similar in size to an M3 screw. You can screw it right into the plastic and it seems to hold fine.You may want to use a few washers to shim it a little and/or file down the point coming out the back.A quick paint job on the numbers makes it a lot more readable.
