math 3d models

While I'm clearly speculating here, I'm also doing the math, and measuring out realistic size components, to make this thing function. Designed to fit within a Falcon 9 launch vehicle, as an <17t plausible payload, to be placed into Low-Earth orbit....

The planet itself measures D with a certain accuracy of .30 - This number makes no immediate sense because in science and math most variables have direct implications that affect our worldviews and perspectives based on new knowledge gained...

Unrolling: Students can practice their skills in math by unrolling a shape using paper or cardboard. They can then use 3D printing technology to create the final product. Results: At the end of this project, students should have: An initial sketch...

I employed basic math to design the board, maintaining logical and even progressions to preserve gameplay logic. I expect project participants to exhibit teamwork between players' peace components. Key objectives in this project include scaling or...

It looks like $16-$20/kg at 100% infill is roughly right, based on my very rough math. James_III had a bit of a hack with some parts so that they fit together properly better now, and here's a link to what he came up with -...

Here is how to work out something basic like the centroid or bounding box from a set of 2D coordinates: ``` import math # define function to calculate bounding box def calc_bbox(points): minX = min([point[0] for point in points]) maxX =...

I want to note: To give this better representation then use simple math for description below since last number is more related with radius R, where one could use it when talking about inner parts if we want more clarification with respect value or...

George Mason University Math 401: Mathematics Through 3D Printing.This set of objects was created for a project where we explored how a calculus topic could be represented through 3D modeling. I chose Riemann sums as my topic, specifically double...

Not a NASA grade math (I'm only a industrial designer ) I’m assuming the 100 tons is earth mass that makes the load around 17000 kg moon weight The two tires OD 8.8m by 2.5m wide, (depending on foam hardness and how soft the ground is) let’s say the...

This is not to say we changed it on the fly, but that before we gave them the coins, we could make a choice on how much to give them.After the trip, the kids have used these coins as tender for their playthings, and math manipulatives for learning...

To obtain a certain Q value and desired F3 frequency - SpeakerGen applies simple math, just like other closed box calculators:http://www.mh-audio.nl/ClosedBoxCalculator.asp Ported Boxes Ported boxes use tuned ports to enhance low-end response (aka...

Can math fill a beach? Can small shapes, ones we can hold in the palm of our hands, cover wide sandy planes? Let's find out together by exploring tessellations. The tessellation is an infinite pattern that completely covers a plane in one or more...

I basically packed in as many math-related concepts as possible. King and Queen's Castle - They like to flaunt their power, so a model of the equation y=x^2 (power of 2) is intricately built into the castle walls. Princess's Tower - The princess is...

A math and science enthusiast, she worked with Charles Babbage, the father of computers. Born on December 10, 1815, in England, Ada Augusta Byron King, known as Ada Lovelace, was the daughter of the famous romantic poet Lord Byron, whom she never...

It's simple math - 2 or 4 multiplied by a single key's gF, plus friction from an incorrect pressure point, and the keys become hard to push. Surprisingly enough, sideways pushing wasn't so difficult, so I decided to rotate the switches to help with...

Do the math beforehand and know your components dimensions, as some of these models can take more than 24h to print (based on specific settings). Large - 58mm TopHat: Fan size is 2x120mm, fan height is 15/25mm, radiator size is 120/240mm, and...

There's just one thing left to prove: that this shape has all sides the same length, and for this, we can use simple math logic. An equilateral triangle on zero curvature has all sides the same length and 60-degree corners; accordingly, a square with...

... These surfaces are also very tiny in scale (arbitrary units and math and all) so require significant upsizing. ... See also, [my Thingiverse collection of algebraic surfaces](https://www.thingiverse.com/ofloveandhate/collections/algebraic-surfaces).

The human brain is capable of incredible feats, from solving complex math problems to creating works of art that evoke deep emotions. It's a remarkable organ that has puzzled scientists and philosophers for centuries. Despite its complexity,...

But not always having motors available for this makes research and math necessary. An Estes D-sized motor is almost the same weight as 18 pennies, provided those pennies were minted after 1982 (pennies were heavier before then). An E-sized motor...

- My original 180mah battery conked out after about ninety seconds of full thrust (because math is hard). Increasing to 450 mah. - The v1 flat beater bar accomplished only a few good hits. This one has a larger bar and now an angled attack. - I...

These scoops were created to simplify the process of working a shake into your macros, eliminating the need for complex math calculations. If I require 35 grams of protein, that's achieved with one scoop of the 15g and another scoop of the 20g. Bulk...

There is a bit of math involved, and this puzzle is often used to teach students about recursive algorithms in computer science, but I find that once you know the algorithm, the puzzle becomes a lot more "mechanic" and a lot less fascinating! I...

(About 90% of the complexity in creating the OpenSCAD code went into the math to get this lip as I wanted it to be precise.) These boxes come in handy especially as an extra protective shell for cardboard boxes, or to serve as a semi-airtight...

The source includes STL and CAD geometry objects, The middle is console input - all python functions like import math and many more which has their implementation from openSCAD to Python. On Right there's an example model with each of those...

This thing is a pair of thin plates with quadratic density functions and marked centers of mass so that you can do the calculation with your class and demonstrate that the math is correct by balancing the print on a string or on your fingertip. ...
