Pendant-cord E26 socket clamps through the 3mm top plate with its shade ring. Feed the plug down through the hole, out the open bottom and through the cord notch at the back. The shade drops over the base's locating collar; print Fit Test E to check the collar clearance against your shade before printing the base. PLA softens at ~60°C: LED bulb only (≤10W / 60W-equivalent), never incandescent or halogen. The top opening vents heat over the bulb; keep the bulb gap (2D panel) ≥ 15mm.
