Ikea concentric ring lampshade adapter

prusaprinters

Adapts out standard light fittings to fit Ikea lampshades. My standard light fittings are 30mm diameter. This will adapt them out to fit 42mm Ikea lampshade rings. Its sits concentrically to the ring and is not visible even on smaller lampshades. Print Settings Printer: D-bot Rafts: No Supports: No Resolution: 0.6mm nozzle, 0.3mm layer height. Really doesn't matter though. Infill: Doesn't matter Notes: This requires some deformation to fit into the ring and stay there. PLA should work for low temperature bulbs but may be worth warming up before fitting it to avoid them cracking. I used Nylon as its awesome, but PLA should work if printed thinly and annealed even for incandescent lamps. For notes on annealing see Rigid.ink, Proto-pasta or even FormFutura guides on the topic. How I Designed This I used Onshape, all files are publically available when used for free. Here is the document. Any pointers on the CAD quality would be much appreciated. Category: Replacement Parts
