Hot off the press .... 23rd December...just in time for Christmas.
This is the first ever tool emailed to space and printed in orbit!
I haven't even had time to print it yet, it's that hot.
I found it here:
http://nasa3d.arc.nasa.gov/detail/wrench-mis
...but the file wouldn't download on either IE8 or Firefox.
It did download on Android, but wouldn't agree to being transmitted to a PC. Finally I made it work by zipping in Android and transmitting the .zip to the PC.
I guess the engineers in Nasa, despite their brains the size of planets, forgot to change the file permissions?
Anyway, here it is for all Earth-dwellers to enjoy!
UPDATE:
I did a print in PLA on my K8200. 0.2mm layers.
I think the centre section is meant to turn and ratchet. But mine fused together :o(
Think the clearance needs to be increased for mere earth-bound printers.
YMMV....
