When building your own Wii smartboard-http://makezine.com/2009/12/30/make-your-own-wii-smartboard/ you can take apart a pen to use for the infrared LED, or print one of these. I made them for a tech camp I work for at the request of the instructor so he would not have to take apart dry erase pens. I measured up the pen the instructor was using, made modifications and created the model in Sketchup. I added the camp name in raised letters as well. This model has no logo.
