Moebius strip. Easy to print, no support needed, but 2 piece.

Long wanted to print a Moebius strip but couldn't think of how to do it without supports and a lot of cleaning up after printing. So this design is unashamedly aimed at ease of printing. It is in two parts so that each can be optimally oriented for printing. The parts are connected with screws.
I've designed an alternative approach using printed tapered pins instead of screws. Printing now. If it works OK I'll post it separately.
