About this 3D model

--> EDIT 2015-01-15: I added a doublesided version with both directions in one tool, righty tighty and lefty loosey. :-) I saw a ton of these already but since my version is a little bit different and I put some work in it I decided to upload them anyway. The NASA Space ratchet wrench (http://nasa3d.arc.nasa.gov/detail/wrench-mis) - first e-mailed and printed tool in space- only tightens. So I mirrored it and created the Righty Tighty Lefty Loosey set :-) http://www.3dwp.nl
