Issue with 3d printing model (naked edges)

I’m trying to model a double curved geometry in rhino, but when i attempt to mesh it doesn’t create a closed mesh, looking closer, there’s quite a few naked edges
I’m a bit stuck with what to do
i created this geometry using a random process involving a string of commands
so it would be great if i could find a way to rectify the existing geometry instead of remodelling

I’m attached a screenshot and the model file for your reference

thank you hugely in advance

Well, first get a legit copy of Rhino, then come ask for help again.


Purchase a legal copy of Rhino and try again.

Ya’ beat me Jim! :slightly_smiling_face:
