About This File
I created my own CAD files for the NSD eye to print because I wasn't happy with any that I found, they all needed some unsightly supports.
I designed these to be easy print (I did mine on an Ender 3, came out great) The front section doesn't need supports, orientate it so the front section faces up and it'll print nicely. The back section needs a support in the middle to print the stem, which broke off easily for me. Tolerances are pretty tight and will need some light sanding to make it a little looser. Then you just have to drill your holes for your allen bolts and you're good to go!
