I needed to cut threads into PLA holes, however the usual thread holders are far too large in tiny positions. So, I created a little holder which can be used with 3 fingers to tap threads into holes.
Use an M4 screw to lock the tap, if you are really needed to. They fit quite snug.
No supports or special parameters required. It may be helpful to use a good number of walls / perimeters to have a strong body.
If you need different sizes, be free and download my fusion 365 archive.
The square hole in the middle requires following sizes:
M3 - 2.65 mm (use 3.05 mm to compensate printed walls)
M4 - 3,30 mm (use 3,70 mm to compensate printed walls)
M5, M6, M8 - 4.85 mm (use 5.25 mm to compensate printed walls)
M10 - 5.50 mm (use 5.90 mm to compensate printed walls)
M12 - 6.80 mm (use 7.20 mm to compensate printed walls)
Have fun :)
