Turbo Mixer

Well I mix plaster, paint and silicone all the time and I hate having a different mixer for each job. So I came up with this design that mixes very well no matter what your trying to mix. I found that this mixer mixes far better than the ones you get at Home Depot and the cool thing about this is that you print it out...

Update: I've changed the blades so that you can secure them together with screws and nuts. Print out the V3.1 blades if you want to use this method.

Update 2: 9/16/2011
OK I was told that the blades were not aligned when put together so I looked at the design again and I know what went wrong. When I changed a blade size length everything was misaligned but still could be used. Now in Version4 everything should be correct. Please let me know is there is any other adjustments or changes that you all would like. Thanks again for all the input.
