A small and versatile shaker with good projection. Made in 2 halves and bonded after beads are added, different thickness on top, bottom and sides gives a wide range of tones. WideFlat version is now uploaded and, you guessed it, it is a wide flat version. and my new favorite.
I recommend .3 layer height, 1.8mm perimeter, and 2 bottom layers on one half, 4 on the other. (make sure to turn off top layer or it will cap it for you) Break glaze and smooth the edge before bonding together by rubbing on sandpaper on a flat surface. ABS with acetone or PLA with superglue both work well, sidewall is thick to help it stick. I am still experimenting with different head thicknesses, but so far .6-1.2 is my favorite. (Update 2-12-17, on the wide flat version I like printing at .2 layer height and using 2 layers on one side and 4 or 5 on the other, it gives a good low-high combo) Sidewall thickness also influences sound, but beware if you reduce it much it will start to be more flexible, which might weaken or break the bond. I use about 1 1/2 tsp of #6 glass beads available at most craft stores. I go for just enough to cover the head about 2ish layers deep. Your preference may vary. Mute and unmute the ends to vary sound, shake end to end or side to side, tap the heads on the palm of your cupped hand or your leg and you will be amazed at the wide range of sounds you can get out of this guy. The pictures of the big blue one show before and after sanding. A big difference in the fit and is a quick but important step.
