Are you like me and find the original EMEK/Etha 2 body to be ugly and fat? How about a simplified, clean body for your marker like this one here? I modeled this directly off Planet Eclipse's Etha 2/EMEK 3D model, only changing the body to make it a nice and simple shape. Note that this body comes with PAL compatibility.

The original eye covers can be used, or my matching style eye covers can be downloaded here as well.

For my simplified, Geo-style bolt back cap, you can find this file at:

The only failure point on the Etha 2/EMEK body is the feedneck mounting boss. Since the feedneck clamps directly onto this material, a bad dive could break here if too weak of a print material is used. To match Planet Eclipse's original material, print with glass-filled nylon, PA6-GF30. Otherwise, printing out of carbon-fiber reinforced PETG is my choice, as it's much cheaper, easier to print, easier to dry, and has similar mechanical properties to glass-filled nylon.

I could try and one day make a non-PAL version of this as well if there's interest. Or, if someone wants to use my file and remake it into non-PAL (for a regular feedneck), feel free and post it here!

UPDATES:

6/18/24: Changed body geometry at back and around back-cap. Extended back further to cover back cap.

6/30/24: Eye covers corrected to fix asymmetry issue; previous right-side eye cover did not fit correctly.
