Handle for small thread taps.
Useful whenever normal tap wrenches are too bulky.

For taps with 3.5 mm shaft diameter and 2.7 mm square head.
Tight fit when the handle comes off from the printer. But after little usage the fit is perfect.

Prints in 35min.

If the fit is still very tight with your printer scale to 102%

The is a smaller version with marked thread size. https://www.thingiverse.com/thing:1701162/comments
I wanted a single and larger handle.

use a brim because the bottom surface is very small
