Please review my model

Hi there,
Some of my customers have a Formlabs and the machine fixes the files itself before printing so the file doesn't have to be perfect but most of the other machines like the Envision tec will reject the file if it's not 100% perfect.
I've had a look at your file and it's really not ready for printing. It has 39172 bad edges and a total of 347 shells.
The Top of the ring as well as the inside sleeve is where your problems are at and I suggest you simplify the design on top as well for casting purposes. You're going to have issues with it too.
Good Luck! :)

thanks a lot maribluruby.

Wich software did u use to diagnose the file, because with rhino 5 i m not able to spot those bad edges and shells.

I use Magics for my stl files but you can also use Netfabb, which is free :)

Thank you so much. I ll try them both.
