Pendant Style Lamp Shade Replacement

Update: Added an STL for an adapter ring for second method of mounting:
- Designed for sockets with a retaining nut up to 40mm outer diameter (E26 or E27 for example).
- The adapter disk locks the shade to the socket collar.
- The disk is threaded to accept 3 screws (20mm length). Files are available for M4, M3.5, or M3 threads to suit your hardware.

Replacement lamp shade for glass pendant lights (over the kitchen counter). Replacement glass is very expensive. But also decided that even though clear glass looks great in the showroom, they shine straight into your eyes. Really annoying.

Old lamp shade dimensions: 100mm diameter, 230mm height, 2mm thick glass, 6.6mm dia holes, 3.8mm diameter mounting pins.

Used "lamp-generator.scad" by creator "seaside" to generate the basic shade model. However customized a bunch. Like adding the mounting collar and cones for additional support to allow hanging. Customized the bottom ring to improve appearance, symmetry, and transition to the spokes.
