Way ahead of you. I scaled it up slightly, so that the replicator can handle it, but it is still only about 1.5 square millimeters, and has 256 spires.
Unfortunately you wont be able to print this with a replicator or any "cheap" printer that I know of. The nozzle diameter of most of the 3D printers whose results you see uploaded to this site are more than 0.3mm. So the prints are made up of 0.3mm wide blobs that are positioned with 0.1mm accuracy. The gecko hairs in your model are far to fine to be printed. According to wiki they need to be 0.2 micrometers which is 0.0002mm
Which is a shame as that would be a very very cool thing to print. Wall mounts that don't require glue or screws! :)
There is a DLP resin printer that's cheap to make but expensive to run that has very good accuracy...
But still not good enough for your gecko idea.
