This is a print of a Wild T3 theodolite in 1/6th scale. I made it as a Christmas ornament for surveyors. For the detailed super awesome print see Wild T3 1/4th scale in FUD. or Wild T3 1/8th scale in FUD.
They can be dyed as they are printed, however, these are printed with a laser sintered plastic and should be sealed after dying for best longevity. They should also be sealed prior to painting. Basically they are porous by nature. I use Future floor shine by Pledge, however, any sealer for plastic will work.
