Wingnut (M4 & M3)

Wingnuts for M3 and M4 screws.
The M3 Wingnut is just scaled down to 79% from the M4 Wingnut.

Nice easy print.  Print with the flat face on the print bed.  Tap in the appropriate nut.

PTEG probably best - PLA might crack when you tap the nut in
Layer height 0.15mm
Infill 100%
Scaled to 101% for Prusa's recycled PTEG
No brim, skirt or supports

Should take about 16 mins for the M4 Wingnut and 11 mins for the M3.

If bed adhesion fails just add a small brim.
