All-in-One Makerbot Filament Holder

This is my design for the Filament Challenge. I used the dimensions that Makerbot gives on their site for the Spool seeing as I don't have access to one. The Base is easily printable, using very little supports and can be used with a peg board or with screws directly. The Lid flips down to protect the filament from dust and UV rays, additionally it features a hole at the top to allow the filament to be fed to the printer without ever leaving the holder. Finally the Arms are attached after the spool is put in place to hold the spool to the Base. Use the Pin to easily tell whether the spool is ABS or PLA.
