Using the original designer’s STL file, I modified the cylindrical section into an octagonal shape. Although there are minor issues, they do not affect functionality, and the print succeeded on the first try.


Print settings:

Printer: Anycubic R1

Material: PETG

Nozzle: 0.4 mm

Layer height: 0.2 mm

Supports: None

Bed adhesion: Brim

Print time: ~1 hour

If you have any questions, please reply to me.
