Rotary tool accessories

After looking at the some pricey name brand rotary tool accessories, at the hardware store... I asked myself, what am I doing!? I have an awesome bot that can make these, so I got to designing and here they are.
Circle cutter attachment- Cut large circles that would normally require careful jigsawing or just use it to for doing more controlled cuts. Use a general purpose cutting bit.
Sharpener attachment- Sharpen anything that needs to be sharpened.
Groove/cutting guide- Cut grooves or guide cuts along flats.
*Still working on testing and printing these all out, but in theory it should work.
***2/19/11 Updated circle cutter to rev.1 It Should be able to use bits that are shorter and it's a little less plastic and the file is way smaller.
You can modify the existing cutter if you printed it by cutting off the top right before the screw holes then drill the hole straight though to get rid of the counterbore.
Circle cutter attachment- You'll need an m4 screw & nut, a 624 bearing a M8 rod and four M8 nuts to assemble. For smaller circles use the slot and a screw. Drill a hole in whatever you want to cut put the screw in tighten down with the nut.
