Lamp Shade Adaptor

A very quickly made adaptor to allow a new lamp shade with a larger diameter ring to be fitted to a lamp base with a smaller diameter rest.Old lamp shade ring 40mm outer diameter, inner hole 28.6mmNew lamp shade ring 60.5mm outer diameter, inner hole 42.8mm, plus a raised ridge and cross supports.The quick fix was print a couple of rings to bridge the different sizes and sandwich the frame of the new lamp shade between the rings. I added some recessed to accommodate raised support structures of the new lamp shade.I only printed in PLA, minimal thickness - due to limited weight to be supported. LED in the lamp so minimal heat generated (I would not recommend using with incandescent globe).I am very new to 3D printing and used Tinkercad to create the (rings) stl file; watching a short tutorial to find out how to merge shapes, convert shapes to holes and group into a single object. (Quite enjoyable to “tinker”).
