I hate to throw a big old steaming turd in the party punch bowl...but if you make one for your self that is no problem...but if you "intend to enter it into commerce" you will find out that it is illegal.
Personally, this is the very first DIY project I am going to tackle. For myself. No sales
Maybe make a work log so others can get an idea of what I did? I do those all the time for my computer case mods.
