I just made this... it came off my printer about 20 minutes ago. I printed it with fine layer heights (.1), and when cleaned it up a bit, it went together very quickly, but it is a bit loose.
I was worried about it being too tight and not being able to get it apart, but mine doesn't have that issue... when I put it down, it almost falls apart.
I printed it at the same size as it came in the .STL, and didn't modify anything.
Printed on my Tevo Tornado with generic chinese PLA, sliced with s3d.
Thanks for a fun model... This isn't a complaint!!! I just thought I would say that I didn't have the "too snug" experience.
