Collection of metric flange nuts including :
M3, M4, M5, M6, M8, M10, M12, M14, M16, M18, M20.
For general purposes PETG, PLA works ok. For some demanding application I would choose tougher material.
If the fit is too tight, I would recommend scaling the model by 0.5-1%.
The author marked this model as their own original creation.
