SLICER AND PRINTER SETUP
Use a translucent filament, white, ivory or similar.
If your slicer allows 100% filling density, select it. Otherwise select
hollow filling (0%).
Except for small lampshades (less than 50mm height), select maximum
layer thickness (typically 0.2mm)
Do not change scale/orientation, do not use printing supports.
If you are getting "hairy prints", reduce the head temperature by 5 to 10°C
and/or slightly increase the filament retraction distance..
