I always put 2 teaspoons of sugar into my tea. This is a pain, since you have to either tear open two little packets of sugar, or else get a spoon for measuring it out. This device makes the whole ordeal go away, dispensing two teaspoons into your cup withy a flick of the wrist.
Threads onto a standard Anchor Hocking-type glass sugar dispenser body, available e.g., at Smart & Final, Wal-Mart, or, on the internet, e.g., here:
1. Obtain a sugar dispenser as described above. Discard the metal cap, keeping only the glass body.
2. Print the "cap" portion of the design.
3. Print the "spout" portion of the design.
4. Clean up the printed parts as needed. The spout should fit tightly into the square hole in the cap. The cap should thread on to the glass sugar dispenser with a snug fit.
5. Glue the spout into the cap, using epoxy, CA-type adhesive (e.g., Krazy Glue), or acrylic cement (if you printed in ABS).
To use, fill the glass thing with sugar, and put the cap on. To dispense, turn the whole unit upside down (so the spout fills with sugar), then right-side-up again (so the sugar pours out of the spout into your cup. It's easy, but you may want to practice over the sink!
