Another Einstein lithophane

Pleased with my first attempt, here's my second. It doesn't look quite as clean as my first, and could probably do with some gentle scrubbing with a toothbrush to remove more strings. The unfortunate horizontal dark line towards the bottom appears to be some old black filament getting dislodged from somewhere.

Sliced with 0.1mm layers, for an 8h22m print, 100mm x 100mm plate.
