An adapter where I need to make a tube structure with 4 mm and 8 mm concentric copper to a silicon tubing.

I had to design a custom adapter to connect a dual-copper concentric flow tube structure to standard silicon tubing. In my design, the adapter has an opening for a 4 mm copper core while the outer lip accommodates another 8 mm diameter copper tube, ensuring both of them are concentric. On one end, the adapter fits with the copper tube assembly, and on the other, it provides a snug, leak-proof interface for silicon tubing. 

I used Anycubic Photon Mono 2 at 0.02 mm layers to print this with a casting resin. You need to add a manual support to the tip of the nozzle shape during printing. See the updated cover image (on an old iteration version):

I upload the step file and public onshape file if you need to change parameters.
