As a gift for two friends of mine who's wedding I am officiating, I slightly modified and printed these two owls based (almost completely) on the excellent model by Cushwa.

I just added the top hat and flower head-band.

Enjoy!

The daring MakerBot Damsels are in no manner of distress -- they deftly define their own world of wondrous wizardry. Making, Creating, and Crafting, they dexterously develop designs for castles, creatures, and contraptions.

Deploying Cupcakes, Thing-O-Matics, and Replicators, dozens of Damsels distribute production precisely for punctual perfection.

Dastardly deed doers and nefarious ninja gnomes beware, the Damsels don’t take kindly to klepto capers and would-be kidnappers.

Greetings Bold Adventurers!

I know you must be pretty excited right now, but please try to contain yourselves while we get thought this final pre-flight briefing....

Your rocket is just coming out of the Replicator now. And let me be the first to say, she’s a beauty. This new model you’ll be flying has that stunning red-and-white color scheme, and a much lower risk of sudden occupant liquefaction.

We’ll be sending you on a daring voyage of exploration and discovery. You're going out into the furthest reaches of the known Thingiverse, with only your wits and those little helmets for protection. We have no idea whats out there... or if it's friendly. But here at MakerBot Space Exploration our engineers have decided its best to just say positive.

Remember, it's the dream of every spool of filament to one day be printed into an astronaut, and you are the lucky few who get to live that dream. Go forth my brave astronauts and see all there is to be seen! Discover all that can be discovered! Meet new prints and learn their ways! Yours is the greatest adventure of our time!

And be sure to take lots of pictures, you know we love a good slide show.

At last, here is the much-requested 100% printable heart gears. No more ugly bolt holes! This was designed along the same lines as the screwless cube gears: thingiverse.com/thing:10483, and in fact uses the exact same center block (though the pins are slightly shorter).

UPDATE: If you lack a 3D printer, you can now buy these from CarryTheWhat at etsy.com/shop/CarryTheWhat.

The size has been increased a bit from the previous version to accommodate the printed pins, so it now measures 100mm across when assembled. Since everything is now printable, it should be easy to scale this design up or down as you see fit. At this size it took me ~6 hours of printing time on my TOM.

This is a 100% printable filament spool based heavily upon randyy's design.

Changes:

Added webbing to arms for strength.
Modified dovetails for better fit (the original required a lot of sanding to get to fit well - for me).
Increased arm thickness for strength.
Increased mount size for strength and more solid connection to MakerBot.
Changed geometry of birdmouth slightly.
Increased size of filament holder so that more filament could be wound on spool.
Added hole in the filament holder.
Beefed up the filament clip on the filament holder.
Enlarged the conical pieces that press fit into the arm for more secure fit.
Added a filament guide for use with Cupcakes.

This bracelet has no clasp; instead you can stretch it over your hand and onto your wrist. It was inspired partially by the Springamathing: thingiverse.com/thing:12053. The design on the outside was inspired by MakeALot's link bracelet: thingiverse.com/thing:7354.

UPDATE: At the request of nycdesigner, a couple of alternate designs are now also available.

Better Living with MakerBot, Episode 2
You probably all know this situation:
You're supposed to ref a soccer game in less than 1/2 an hour and you cannot find your whistle. You're screwed!

But from now on you're out of trouble: Fire up your trusty MakerBot and print a new whistle in 26 minutes!

This object prints the pea right inside the whistle. Since the pea is connected to the rest of the object only at one tiny point, it's quite easy to break it loose after printing with a small screw driver or tweezers.

I probably pushing luck a little bit with bridging the top layer. So far I printed the whistle twice without problems.

As always, I added the object as .obj file (wavefront), which can be imported into AOI and Blender.

The gcode file is the one I used to print the whistle on the image. The gcode file contains an experimental raft with additional "blobs" on the second (interface) layer.
You might want to generate your own gcode file with skeinforge settings, tested with your MakerBot. Be sure to setup Skeinforge to create an (almost) watertight object, since the whistle won't whistle if it's full of holes...

[Update]
I added a second version of the whistle. "Whistle_v2" is an attempt to fine tune the object a little bit. My brother (he's a pipe organ builder) gave me some tips how to optimize the whistles mouth. Whistle v2 should start whistle with less airflow than v1 and thus be (somewhat) less loud. I also downsized the pea a little bit and changed the shape of the lanyard loop.

Whistle v1 is still available for reference and also since it's more "tested"...

Since you blow the whistle with your mouth, be aware of possible problems concerning "food safety" of printed plastic. See the blog post "For foodies out there" ( blog.thingiverse.com/2009/09/13/for-foodies-out-there/ ) for more information.
