Thin Profile Whistle

Thin profile whistle, originally a pendant design but adapted to be printed using FDM printers like the Up! or the Makerbot.

... Sorry about the logo/URL on the back, feel free to remove it. I'll upload a clean version soon [once I boot back into windows].
Edit : Uploaded a 'WTF' copy instead :P Please print one, colour it in and post a pic? :)

Can someone with a MakerBot please try print this and tell me if it is OK? I've tested on the Up! and its very loud :)
