Bit of a PITA to fix. Only two out of the 8 files are usable. These also need to be run through netfabbs STL fixing service then you need to cut the first couple of layers off the bottom of each object (once you've got it rotated correctly) as the flat edge isn't flat.
Once all that was done I scaled the while object to 200% then scaled the Y axis a further 150%.
I'm really pleased with the outcome but would love to print one at 0.05 resolution but it'd take 30+ hours!
Another annoyance is that it used up all my silver filament so I'm having to print the other side in purple.
Anyway many thanks to the original creator as once you can print it properly its a great model!
