FreeStyle Libre dust protector

I post this as a remix. But it is rather a remake that is better suited to print without support.

Personally I printed with
- 6 perimiter
- 0.6 mm nozzle
- 0.15mm layer hight
- no support
- no brim
- PETG

If you have a smaller nozzle you might want to increase the number of perimeters.
