Stationery rack

As a student, I often copy a note or draw a key point. The pen is placed directly on the table. Sometimes I accidentally drop the pen to the ground and cut off the water. Otherwise, the book often presses the pen. I have to look for it every time I want to use it, so I want to design a stationery stand, and I can put the stationery on it whenever the stationery is used up.
