The wood composite seems well suited for printing some custom parts I designed to supplement the Lillabo Train Set from Ikea.

The parts printed out well on the first go, with only minimal clean-up required due to the oozing. The circle part of the buffer still had a hole in it even though I set the solid layers to three (infill=20%), but adding a red sticker easily solves that.

It makes me think that a useful feature for a slicer would be to gradually increase the infill for the last few layers, i.e. 20% on layer n-3, 40% on n-2, 80 on n-1 and then 100% on the top.
