So I'm sat in my workshop playing around with my printer and doing some sorting out whilst I'm at it.I have a scrap of wood that I think will make a useful little shelf but I don't have any shelf supports.Ding goes a light bulb above my head so applying a little learning about freecad and a few minutes later it's on the wall :)I've printed this with 2 perimeters, 2 solid layers and 40% honeycomb infill and it works.Surprisingly strong for a little thing.
