Summary

I made orubap's Minecraft torch nightlight, but the head was so thick even a bright LED bulb made it hardly better than a candle! Also, if you printed at normal settings, you could see the cube pattern inside and it looked ugly. So I reduced the thickness of the head to 1.5mm and now both problems are solved!
No special configs necessary as it'll be 100% walls by default. Also, I recommend setting the supports angle to 46º to avoid a lot of unnecessary supports.
