Yet another shelf.
As I wanted to use curtain rods (16mm thin wall steel tubes), I decided to design it myself.
Printed with eSun PLA+ with 3 layer walls and 25% infill - seems to be very strong.
This is not a fast-print model. I just wanted this honeycomb look, but it is making it slow to print due to the big area of external walls.

The author marked this model as their own original creation.
