Some time ago I bought an headphone stand made of transparent plastics (see photos).
I am just starting to learn Fusion 360 and I recreated in it.
I did not have the time to print with my Creality CR-10, but I will do soon.
If you can improve please do it and share, just say my name... ;)
The angles are all 45° so it should be printed on any 3d printer.
I give also my settings for CURA e for printing it in PETG (it is a prototype at 25% size project)
I used Fusion 360
Just as a beginner, but it is a simple object.
