I have a pair of cheap solar lights from Lowe's that provide a few hours of illumination around my front steps in the evening. Over the course of the winter one of them became uprooted and I misplaced the spike the holds it in the ground. So, I designed and printed a new one! The original was completely cylindrical, but this one has flattened sites to print easily without supports. Still fits perfectly snug. I understand PLA is a bio-based plastic but I'm not clear on exactly how quickly it biodegrades. So, this is partly an experiment in PLA composting - I will stick this in the dirt and see how long it lasts. (Rotate to lie flat before printing.)Printed in brown PLA with my Printrbot Simple. 0.3 layer height, 3 walls, 4 top/bottom layers, 0.2 honeycomb infill. A few cracks and a bit of curling in the print, due mainly to the fact that I used this print as an opportunity to fool around with the fan speed and feed rate as it was printing to get a better feel for their impact.
