Simplest and fast printable Tool holder for CTC pro b / Anet A8 / Prusa i3

Do you need a tool holder for your printed, but you're afraid of waste a lot of filament and time?
i had the same problem, and for that reason i created this design that needs only 9m of 1.75 filament ( 29 gr. .. then around 60 cent for a greentech filament ) an hour and a quarter to have your work area tidier!
Like always i leave a 3d file for make changes and improve this design, that i admit.. it's not the best ever seen.
