ER16A collet wrench 25mm

I made this wrench some time ago when I was missing the correct 25 mm / ER16(A) wrench size to change collets on my AMB 1050FME milling motor. 

As I am only changing the collets and the print is pretty strong until now, I never bothered to buy a metal one.

Printing

The print gets stronger with more plastic, so 3 to 4 perimeters and a higher infill like 25 to 30% rectilinear worked for me until now. 

Disclaimer

If printed in plastic, be aware to not be hurt when the print breaks or splinters if it is used too heavily.
