# Summary

My brother likes to drink tea, but not the kind that comes in teabags. He likes gourmet teas which have to be measured into a tea strainer for each cup, and his favorite tea requires him to measure two teaspoons of tea leaves to make a cup of tea.

It turns out that nobody makes a 2 tsp measuring spoon, so he's always forced to measure two scoops instead of having a conveniently-sized measure which corresponds to exactly one cup's worth of tea leaves.

This was an obvious application for a 3d printer. I designed a 2 tsp measuring spoon, using a hemisphere for the scoop so I could calculate exactly how big it needed to be. I gave it a large handle which allows it to sit exactly level on the counter, and as a final touch, embossed "2 tsp" on the handle so there's no doubt how much it holds.

But why stop there? I occasionally have to measure 4 tsp (or 1 1/3 Tbsp) when I'm cooking, so I designed a 4 tsp measuring spoon. This lets me get in one scoop what used to take four.

Then it occurred to me: there are all kinds of useful sizes for measuring spoons which are impossible to find in the store. In particular, even the best gourmet cooking stores never seem to carry measuring spoons in increments based on mathematical and physical constants.

Hence, my set of Measuring Spoons in Hard-To-Find and Useful Sizes.

The sizes included in this set are:

2 tsp
4 tsp
pi tsp (pi is the ratio of a circle's circumference to its diameter, see http://en.wikipedia.org/wiki/Pi )
alpha gallons (alpha is the fine structure constant, see http://en.wikipedia.org/wiki/Fine-structure_constant )
e Tbsp (e is the base of the natural logarithm, see http://en.wikipedia.org/wiki/E_(mathematical_constant) )
phi fluid ounces (phi is the golden ratio, see http://en.wikipedia.org/wiki/Golden_ratio )

# Instructions

1. Print
2. Keep around the kitchen
3. Make puns about baking pi (optional)

For those who wonder why these measuring spoons are English rather than metric: If you're going to make an irrational measuring spoon, it only makes sense to use an irrational measuring system, too.

This is awesome. I am looking to do something similar but am new to 3d printing. Want to ensure that it would be cheaper to print than purchase a generic scoop wholesale. Rough idea on the printing costs of the largest one you made here?

The printing costs will vary with the printer, print settings, and material.

But really, if you're hoping to beat the wholesale cost of a cheap plastic measuring spoon, it's not going to happen. Those guys churn out pieces by the million, and their manufacturing cost is only a little above the cost of plastic pellets. 3D printing really isn't suitable for mass producing parts which can be injection molded.

LOVE YOUR MEASURING SPOONS - NOW HAVE A 2TSP.

These are great for making your own mixtures of non-petroleum and no VOC cleaning supplies - borax, vinegar, soap, lemon juice, soap nuts (Sapindus tree), baking soda.

We should probably add standard sizes (e.g. cup, pint, etc) for people in less fortunate countries that are on the Metric system. At least until they convert.

be careful with this. It's impossible to clean out all the little honeycomb space between the lines of plastic. I guess it's ok if you're going to measure tea, then boil it in water, but be sure to never let them come into contact with food that won't be cooked.

After the first print, you can't ever get these things clean.

Some places print ceramics, so if you're happy with the design, you should have some made.

Aside from that, these are great. I want some of these for my waffle recipe that i always have to cut in half.

If your printer leaves gaps on the outside surface, painting with a thin mixture of ABS and acetone should fill those in and seal it up very effectively (assuming you printed with ABS). ABS is dishwasher-safe.

However, keep in mind that the ABS filament most of us get is not food-grade (though it is nontoxic). So while it is probably safe to be in contact with food, there is no guarantee that there won't be something in there you don't want. Just to be on the safe side, I printed these in natural ABS to
minimize the risk that the coloring agents might not be safe.

I don't know of any place you can get 3D printing done using food-grade materials. On the other hand, the actual risk of contamination is pretty minimal, especially if you're measuring dry ingredients.
