About this 3D model

Model only, I needed the shape for design. $10 micro engraver that runs on 2 AAA batteries available from amazon, harbor freight, and Taiwan. 2 versions: 'noprint' is the complete model. It isn't unprintable, it's just beyond my printer, at least not without lots of support. The other is in several pieces: the head,a body half segment, connector peg, and segment with peg. Print the half twice, thats the battery compartment. I designed it to use 3 3mm filament segments in a triangle, glued. The connector peg is the same as using filament. I used this model to design a microengraver head mount. http://www.thingiverse.com/thing:30520
