Bobble Shakers !

The weighted, round bottom of these shakers makes them wobble and spin around without tipping over. If you use BB's to weigh them down they'll also make a cool Maraca-like sound when you shake them. Bonus!
I used a .5mm nozzle with .15mm layer height in PLA for my build and the threads came out perfectly on my super-duper Tantillus printer:

Just added a couple larger cap STL's (the 37mm ones) after BrokenDrum informed me that most printers probably won't be able to Â make the originals with a tight enough tolerance.Â
Thanks to BrokenDrum for the heads-up and for the STL's that he created - I should have posted them a couple weeks ago when he sent them to me, but got lazy.
Thanks Helmi. It means a lot to me that you'd say that because functional/aesthetic design is something I'm trying to move towards in my career. My ego is purring like a kitten right now :)

1. Print each part. Remove the support portion of the BottomHalf piece and sand down the rounded bottom so it's nice and smooth.
2. Fill the BottomHalf piece with a weighty material. I used BB's as the weight because they're heavy and make a cool shaking sound when you dispense the salt/pepper, but all kinds of other things would work too. If you use a fine-grain material like sand then I'd recommend gluing the seam between the TopHalf and BottomHalf pieces so the material doesn't fall out.
3. Balance a #8-32 x 1 inch long (or M4 x 25mm long) flat head phillips screw on the top of a screwdriver as shown in the second attached image, then lower the TopHalf piece over the screw carefully so that the screw goes through the hole.
4. Put a few drops of glue in the hole of the Plug piece and then insert it into the hexagonal hole in the bottom of the BottomHalf piece (careful not to spill any of the weight material :)
5. Place the TopHalf piece onto the BottomHalf piece and tighten the screw into the Plug.
6. Fill the TopHalf piece with salt or pepper or whatever else you want, twist on the Cap and bobble away to your hearts content!
*The Solidworks file attached has the TopHalf, BottomHalf and Cap parts all in the same file (as separate/split bodies) if you want to play around with the native file and change stuff. I was thinking of making a Cap with the Steven Colbert bust, but haven't tried yet ;)*
**There are two different Cap piece STL files - one with a rounded top and one with a flat top**
***Be sure to use 'food grade' filament when printing the parts if you're concerned about the health hazards of your spices coming into contact with non-food grade plastics***
****You can mix in a lighter weight material with a heavier material to get a good weight for the base. I ended up using BB's and little plastic pellets in about a 1:1 ratio myself, which gives a nice bobble effect when 3/4 filled with salt.****
