My take on Tada3's model from thingiverse. https://www.thingiverse.com/thing:3175389 I optimized the dimensions so it can be printed in vase mode. The included shade stl (approx 140mm dia x 200 mm h) can be installed as is on a pendant lamp holder or stand lamp with fitting nut. Glue on the base adaptor (for 80mm dia lamp fitter) if you are installing on a lamp fitter. Use short filament as alignment pins to align to shade. If using PLA, a few coats of clear lacquer spray paint is recommended to protect it from becoming brittle. Note that errors will occur when the number of cells for each ring or stack count change. If so, just edit the affected combine feature and select all the tool bodies and it should be ok.
