I printed the head and as expected, the result isn't perfect, but good enough for me. Should be fine with bit of post processing.

Sliced with KISSlicer, 0.1 mm layer, 0.45 mm extrusion width, 2 perimeters, supports enabled (support threshold 71 degrees). Printed on Prusa i3 MK2. Material is white PLA (Cel Robox), @205 celsius, with part cooling on. I haven't run any calibration for this material, as I normally don't bother.

Would be interesting to try with another slicers, Simplify3D and Prusa's Slic3r (has 0.05mm quality preset).
