Use this tool to measure out 1,2,3 or 4 servings of spaghetti! (I made a smaller one (1,2 and 3) servings for smaller 3d printers 120mm.
The holes are 20mm, 28mm, 35mm and 40mm. This amounts to about 315 Sq mm per serving.
Fun math fact.
Whenever you double the diameter of a circle, the area quadruples. That's why the small hole (1 serving) is 20 mm and the large hole (4 servings) hole is 40mm!
The area of a circle = Pi * Radius Squared
Oh yea, remember Pi from school? 3.14
That only means that every circle is 3 times further around as it is across.
(It is just a constant ratio between any circle's circumference and diameter).
So... The small circle is 60 mm around and the largest one is 120mm around
(well, plus .14 but who's counting)
Who knew math and spaghetti were related!
