The file 'Darts Flight 3D Printer Model' is (stl) file type, size is 2.1KB.
Replace your bad paper flights with even worse plastic ones.
Might work well, still untested.
The model is 0.3mm in height so keep an eye on that initial layer size.
EDIT 2019.03.08:
Broke on first use, It'll work as a emergency replacement, but not for long term.
Designing a new version soon.
