hi huys i make this model but i get this error I think I tried everything but I couldn’t solve the problem can you help me?
its blender file link :
hello, your link asks for an authorization, we can’t download 
sorry , i fixed it
It’s now accessible but I can’t see any download link 
i fixed it again sorry
In Edit mode select all and press Shift N to recalculate the normals, and you must have overlapping vertices so press M to Merge by Distance. Also I’m not sure it’s a good idea to give thickness to your mesh
I’m sorry, I don’t quite understand, can you do it and send the file to me?
bro thank you soooo much , I’ve been trying to fix it since yesterday
