Made this design a while back, when I needed a way to hang a light bulb somewhere above the bathroom mirror. Socket width is customizable; seems I hard-coded the slot-width somewhere… :-sConceptualized in my head, designed with OpenSCAD, printed with Ultimaker Original (PLA). Pictures are actually from a second iteration: After a while, the PLA seems to have loosened a bit, so I re-printed it with a slightly lower socekt-width so that it'd fit tighter.
