About this 3D model

I designed this spool holder for the 3DPN design chalange (Hi Joel). It is designed to be printed as one piece, with no supports needed. My print time at .2 layer height was a little over 5 ours.This holder is meant to hang on a .75"x1.5" board, and can quickly be moved to any position you want, however it locks in place well because of it's low center of gravity. The width of the base (40mm) is narrower than a standard spool, so it should not interfere with other spools placed in the rack. Thanks for looking.
