Mobius (Moebius) strip in stand. No support needed.

I've attempted to design a Mobius strip that looks the part (unlike my previous offering which was minimalist) yet remains easy to print. Hence this vertical design.
IMPORTANT NOTE: I found that is much easier to print at 2x size.
I've posted 2 stl files, one with stabilising posts and one without. I think that the stabilisers help at 1x size, but unsure at 2x as I haven't done a print without them.
Printed in DiamondAge PLA on an Ultimaker 1.
