Firstly thanks for your review. I got the STL meshed file and make it real by 3D printer. right now as a 3D print newbie, I have a no idea which tools shall be used to pattern the whole holes in the face of box, could u give some advice and steps what tools should i use.
This is the easy part. Just draw a sketch with holes. You need to make a couple of them and then just copy with pattern. After that just extrude from the box.
Here a little bit harder because there is no such thing as wrapping in S3D. Only way you can go is projecting holes on a body from sketch (or even sketches) placed by appropriate angle to that rounded corner.
Also, printing round holes is a mess with a 3d printer as it would insert support into every little hole. I would suggest shaping the holes so you don’t need any support.
