Description
Fans of the Portal game series will recognize this vintage “Aperture Science” warning sign, recreated from scratch and designed for 3D Printing.
Put it by your printer, in your kitchen, in the bathroom, or wherever chemical hazards may exist!
No AMS is required, just pause at layer 13 to change filaments for whatever color combination you want.
Photos show it printed in PETG, but any filament will work--just be careful with ambient temperatures so the edges don't warp. For those with larger print beds, scale X and Y, but leave Z as-is.
The profile has enough top layers to make up for any translucency in your filament, but if you're using something very opaque, you can reduce the number of top layers.
Remember--Aperture Science: We do what we must because we can.
