ok i had success with it your advice. However im having a small problem there is a thin ring being displayed i cant get rid it. also i just want to chrome the inside of this piece is there an option to do that? i did see chroming but just need the inside. if there is no option its ok ill be ready to order.

Please ignore the ring - it's a 3D preview imperfection.
Use Comments to Machinist to specify chroming of the inside surface.

i figured it was but it will not let me complete the order it says revise design. Is there another way i can submit it to get a quote? also do you have black mirror finish? Like a black surface but with reflective property. thanks

We got your design via mail. Looks like your part is larger than we can machine.
We replied about finish in another topic.
