Bicycle Mascot, with flapping wings

pinshape

SummaryEver felt inferior to all the Rolls-Royce owners in your neighbourhood, when getting on your rusty old bicycle for the way to the office? Work colleagues honking and jeering at you when passing you with their Bentleys or even a petty Mercedes Benz? Well, there's an end to your suffering! Pimp up your old bike with a stately mascot. Even better, a wind-wheel, concealed behind a classic chrome grille, drives the mascot, so when riding your bike it will start flapping its wings, turning the faces of all those luxury limo owners green with envy! The Bicycle Mascot works just like a good old toy almost everybody had as a child: the "jumping jack" (or "Hampelmann" in german). A pullstring is used to lift the wings that will drop back due to their weight once the pullstring is released. To automate this process while riding your bike, I decided to use a wind wheel with a slightly off-center pin to which the pullstring is loosely connected. The relative wind drives the wind wheel (an idea I used before in my bicycle bubble machine) which will make the off-center pin periodically pull the string by approximately 1cm. This is easy to assemble, but needs some patience to get it right ...

However, for the mascot and the grille I used 40%: the mascot rests on a very small area and its head has only a small connection to the body; the grille has the mounting clips which have to take some strain. For the wind wheel and the arms, you will have to use support. Be careful during removal, as parts may easily snap. The mascot body may print well on good printers without support, but I'd use it (it's much easier to remove than the support for wind wheel and arms). The rest of the parts don't need support. Especially for the mascot body and the wings, printing with a raft is a good idea. The rest printed well without for me. I decided to spray my printed parts silver, mainly because I didn't have any silver filament at hand.Post-PrintingInstructionsPlease see my instructable on instructables.com on details of how to assemble this: http://www.instructables.com/id/Flapping-Bicycle-Mascot-Fully-3d-Printed/ Please note that while the arms work fine for me, the wing-version does not yet, for some reason they're getting loose. I'd stick to the arms for now.Custom SectionLegal stuffI generated the woman figure using the character creation tool “ManuelbastioniLAB” created by Manuel Bastioni (www.manuelbastioni.com); all output of this software is licensed under creative commons attribution license.
