M3 Round Screws (Hex head) and nut 2mm-27mm

Expectations:

Don't expect a screw that is strong as its metal counterpart, but it will do the job for low stress applications.

The screw may need to be resized because of inaccuracy of FDM printing.

Print settings: 

• Speed: about 5mm/s (because they are small)
• Infill: 20-100%
• Number of walls: 2-4 

All screws and nuts (conical):

• M2
• M2,5
• M3
• M4
• M5 
• M6

Have fun printing! (and ask if you need any help)
