HAL 9000 brain-key stem

Here is a representation of the Burg Wächter E7/3 key or E7/2 ( the second numeral dictates the number of keys in a pack) to go with the print of the memory shut down key used by Bowman when he turned off HAL 9000 in the epic film, 2001 a Space Odyssey.

I tried printing with PETG, but got better results using PLA as it came out a bit sharper at .1mm resolution. Attached photos show various stages of painting. One I finished with Silver paint, the other is done with a chrome Molotow pen.
