Just finished in wood filled PLA, .25 layer, 1mm shell/top/bottom 50% infill. Too tight to turn without major force, sheared off the pin on first attempt to seat all the way even after sanding the base and reaming out the cap slightly. Going to print new cap at 101% and that should fix it. Going to try and stain the wood PLA for an old artifact kind of effect. I'll post pics when I get it done and working good with all the details.
