Farscape DRD eye unit

The DRD (Diagnostic Repair Droid) from the TV show Farscape is/was available from Goldenarmor.com as a resin Kit but has many inaccuracies. One of which is the eye unit which is way too big. This is a replacement for that.
Print/paint the the eyeball hemisphere in clear/translucent filament, unless you can find a 2.1cm diameter hemisphere somewhere.
The main unit is matt or satin black, I found black filament looked good as is.
The centre hole is sized for 3/8" (1cm) styrene tube from Evergreen Scale models which is used to mount the corrugated tubing which forms the eye stalk. This can be split wire organiser tubing though I found air hose from an inflatable exercise ball better plus it came with handy tube connectors which can be glued to the DRD shell for easy mount/dismount of the eye stalks.
