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

I have a concern of messing up the head alignment by dragging or jamming, or twisting.

I might need to make a suspension system; maybe rubber bands, maybe tie wraps in loops. If you crash the bit into the bed or anything else, the engraver needs to have some give and move, or release completely.

The power button on the front could be jammed on in a housing, and the battery compartment door on the back used for power. It twists on and off like a flashlight.

Neat - Thinking of rigging a little regulator circuit to the cooling fan on my extruder. Then I can control it in software with out adding any more wiring to my ToM....or I guess I could even use the ABP Conveyor lead....but then I have to worry about that getting caught and ripped off.

A great I idea I can use this with my G-code extension for inkscape and can engrave now instead of just plotting. - well not with the model anyhow. I didn't know they sold a small pen-like engraver. Thanks for putting this up.
