This is a thing I created after spending hours (and feeling wrist pain) while changing the strings of my guitar...=P
How long do you take to change a guitar string? Well, if you do it manually, maybe 5 to 10 minutes (incuding tuning). What about all the six strings?
Fear no more!
All you have to do is to print StringItFast (it only takes 15 minutes!) and attach it to an Electric Screwdriver (as shown in the pictures)...Have fun!
