About This File
These are "midgrade" prop replicas (detailed enough to be seen in relative close-up, but no moving parts or electric bits). Printed in ColorFabb Black PLA/PHA and Ultimaker Metallic Silver PLA, then they were sanded and painted. There are a couple of non-printed parts on one of them (a chunk of clear acrylic rod, and a watch crown), but apart from those they were printed on an Ultimaker 2.
The model files (and more detailed information on the finishing process) are available on YouMagine and Thingiverse.
