Simple Thread Spool with hole

I made this thread spool for my mother. She does cross-stitch and uses cardboard/paper ones that are very weak and break a lot. These are ductile but much more resistant. They are the same size and have a hole in the upper area. She uses it to roll the thread using a small accessory (I'm sorry, I don't know exactly what it's called). I haven't added the cross-stictchs that other models have because my mother always complains that, on plastic spools like this, the thread usually breaks if it gets caught in them. So I haven't put them in. The spools prints very quickly. It measures 40 x 38 millimeters and has a thickness of 0.6 millimeters (three layers if you print with a layer height of 0.2 mm). It prints in two minutes using only one gram of filament (33 centimeters, to be exact). You can find the STL for a single unit and two 3MF files: one with 35 units on the plate (compatible with Bambu Lab P1S) and another with 36 units on the plate (compatible with Bambu Lab
