Honeycomb Lampshade

My take on Tada3's model from thingiverse.

I optimized the dimensions so it can be printed in vase mode.  Set bottom solid layers to 2mm (10 for 0.2 mm layer height).

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.  Mounting hole size is 40mm diameter and fits Euro style lamp holders such as Ikea Hemma.

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.

.f3d file for Fusion 360 included with parametric values you can change so you can customize your own.   
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.
 

Adapted for pendant lamp use.
