This design for a better back scratcher is easy to print and assemble. Building a better back scratcher seems like it would be easy, and I thought it would be. Unfortunately, I am really picky about my back scratchers AND my back was quite itchy. This back scratcher was my 7th iteration and I think it is pretty darned good. I hope you enjoy printing and using it. Print out the file, it should be three pieces. Then glue the pieces together. I used gel-style super glue. It worked great. Scratch your back. Let a friend use it, but only for a few seconds and then start printing another one because I doubt you are getting that one back. This design is part of a project I am doing called MakerLove.com. MakerLove involves making items that you might be embarrassed to buy or ask about in the store. I believe that with the advent of Makers people will refuse to buy these items and will make them in their home. I have a website: http://www.MakerLove.com. I hope you will visit it.
