I got tired of the old 3D printed lampshades for our self-built LED lighting. So I designed new ones with Ebony woodfill and blue.
Dual extrusion print, two parts: bottom (spiralize mode) and top (wood and blue) with a slit to get the cable through. The woodfill seems to have some air in it, tiny holes and crackling sound during printing.
UPDATE: I played around with extrusion rate and decided to consider the tiny holes as a feature now
