Since I received the message of the question, I will explain how to make a sunburst color face plate.
1) Create and print a face plate model with two steps in a staircase pattern.
2) Draw a shape that goes into a deep step inside with illustrator and print it on the label sheet.
tips: You can create accurate shape data by saving the drawing data created by FUSION 360 as PDF and importing it into illustrator. It is good to offset the shape inward by 0.2 to 0.3 mm to make it smaller.
3) Attach the printed label sheet to a thin natural wood sheet and cut the natural wood sheet with a design knife. After cutting, remove the label sheet.
4) Use Illustrator to create a shape that fits into a shallow step on the outside. Use Illustrator or Photoshop to create black, red, and yellow gradients and logos. Print it on a transparent film (eg OHP film).
tips: Invert the characters.
5) Cut the printed transparent film according to the outer diameter shape.
tips: Paint the cut section black with a felt-tip pen to make it less noticeable.
6) Stick a natural wood sheet on the base of the face plate.
7) Apply a thin layer of UV resin and cure.
8) Apply a thin layer of UV resin, attach a gradation film, and then apply UV resin.
9) It cures by exposing it to UV light.
10) Apply UV resin to the entire surface to flatten the surface.
11) It cures when exposed to UV light,
12) Paint with clear lacquer using an airbrush.
13) Take a closer look and enjoy yourself, and you're done!
. And thanks for the method of the previous page on the tubes/shell assemblies , it’s a bit long to do but it works perfectly
