3D printing 2" EPs from Binocular Parts

[Stonius (Markus)]

Just got a 3D printer and stumbled across this project on Thingiverse.

This guy designed his own 2" EP's from old binocular parts.


Seems like a cool project for someone who's curious. I'm not game - I know that I do not know enough to get that working, but it might be fun for a tinkerer.

not sure its something id tackle either, but damn you can do some amazing things with a 3d printer these days. Prices on good rinters have really come down and filament doesnt cost too much either. Great way to test things out

Plossl eyepieces are basically made from two achromats facing each other. I suspect that's what he was making. However since Plossl's are relatively inexpensive, I can't see any great advantage. You might save a few dollars but off the shelf eyepieces are likely to give better results.

I've made two of these but not 3D printed.
They are Di Plossl/Double Plossl and use 4 bino objective lenses in each. They have bigger fields than ordinary Plossls.
They are the two left ones in the attached pic.

Hi I saw the project as well and purchased a couple of Ebay 7x50s to try it. Then I saw the Astrosky web site and decided to 3d print some offset binos. 4 proof of concept projects later and this has morphed into some 80mm 3d printed binos with some brass tubes and I'm working on a set of 127mm binos. The old 3d printer was v slow so I've invested in a Creality k2. This is ripping through the trial, test, fix and reprint cycle. PM me if you would like the stl files or some pics.
