About This File
CREATOR's EDIT: My apologies, I only just realised this has 8 rods, not 12 going around the eye. I'll leave the files up for now in case anyone wishes to modify them, as I don't have the time right now. My plan is to sand off the rods printed on the eye, and make/glue the vessel tubing as a separate part so to not bin the one I currently printed. Just wanted to be fully transparent about this mistake!
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!
