Box from empty spool (Editable)

To use empty 0.75 kg spools, I created special boxes that go out of it in a circle. Created for coils with the following parameters:
- outer diameter 202 mm
- inner diameter 108 mm
- height of the winding part 45 mm

I get such coils from the Ukrainian store https://3dfilament.com.ua/

Also I have attached the original f3d file for Fusion 360 if someone wants to do it for their coils.

Printed with a layer height of 0.3 and a nozzle of 0.4. With such parameters, it took me about 1.5 hours and 22g of plastic for one of the six boxes.

For assembly, 12 m3 screws with a length of 10 mm are required. I recommend threading the holes in the boxes.
