About this 3D model

Hey there people! So I was looking to buy a lens hood for an old lens I have for an old camera. Seems like no shop had on stock so I decided to do some research and try and find one to print. I had no luck in finding this model so I found an EW-73B that was very similar and remixed it. I cut the bottom and twisted 90degrees the top in order to have the long "wings" above and below. Resized it to fit this little monster objective and here it is. I hope it helps and if you find any flaws, let me know. Cheers
