math 3d models

Well, now I know why no one else has really done it: it requires an excessive amount of trial and error, and math. I'm excited to see how I can port this into OpenSCAD. So yeah, about a week later, and a lot of time I should have spent studying or...

The maths and principles behind this design are the same as those for my CD Polyhedra, https://www.thingiverse.com/thing:4734057 , including compatible truncation faces sizes. As well as putting beer cans together, I have printed compatible parts...

I took measurements from a digital tach, instead of doing the math. Will be doing some sort of planetary gear reduction with a stepper motor in a future update. My drill method is working fine, now that I have a way to measure the rpm's. It is...

Magnetic spheres are used to make 3D printed polygons that can be used as an educational math tool, a fidget device, or a unique set of magnetic building blocks.  The polygons can be used to make polyhedrons and other fun shapes.Triangles, squares,...

Number of 1/2 turns for frame advance (6 frames total; 1/2 of a 1/2 turn is a 1/4 full turn - any confusion is not my fault, blame your math teacher lol) - Arrow at start edge of first frame 15 turns Frame 1 5 Frame 2 5 Frame 3 4 1/2 Frame 4 4 1/2...

You'll need to do some math... take the length it was supposed to be "30" multiplied by the current step per mm value "80" (30*80=2400) - then divide it by the measurement of the rod. So for Tower X, it should be (30*80)/31 = 77.42. For Tower Y:...

... the coolest thing I've seen here!" or many other similar derivatives. I also made a cute little math facts table using the same process. Not as large but still had 600 cube pieces to put together. Phew. ... https://www.thingiverse.com/thing:3830320

This entry for the Makerbot Academy Math Manipulative Challenge is a comprehensive set of eight hinged polyhedral nets and five types of modular snap tiles for assembling various types of polyhedra. Printability: These models were all specifically...

Michael Tritle MATH 401 3D printing George Mason University 09/18/2019 Type 9 pentagons must satisfy the following criteria: If A, B, C, D and E are the interior angles and a, b, c, d, e are the lengths of edges of the pentagon, then 2A + C = 360°, D...

Corner", so you can fool around with the ballistics of the rounds, and make those fancy curly diagrams as listed on page 236 of Mc Coys book, also listed in the "Public Release EPR" file.I advice you to use a copy of "Maple" Math program, or a...

The files: * A picture of my remix of the PCB seen in Heliox dice videos * The Schematics, improved for better reading, provided by KiwiGrinder (thanks!) * New old PCB V2 size 2*19.6mm on each side – do the math yourself! One layout picture has an...

 I spent weeks building his design up in Solidworks, trying to understand the math involved in the CAM mechanism.  Once I had his model rebuilt, I then started playing and having fun with tweaks and changes.  You will notice the v3.04 on the inside...

... I get perfect results: a snug fit. I do this because it makes the math and modeling easier and more precise than needing to add 0.45 to 0.48... divided by two (0.225 to 0.24) to everything.... ...0.4 divided by 2 is 0.2, which is simpler.

Mickey Mouse's Mandelbrot set Sarah Boyt George Mason University Math 401 Mathematics and 3D Printing Brief History: Once upon a time, in the early 1800s mathematician Pierre Fatou became interested in the iteration of the equation c→c^2+k where c...

Fast Example: My ROM X Stepper settings = 80.421 When I measure my test print, it should be 40 x 60 mm but I got 39.7 mm Then the math: Size (What you want it to be) × Your ROM Step / Size you got. (40 × 80.421 / 39.7 = 81.028) So just put 81.028 in...

If my maths works, then if you have the connectors opposite each other then that makes 122mm. If you know your Sectors Mechanicus and Imperialis, those should be very familiar numbers. The sphere itself is suspended with a centre at 61mm off floor...

Objectives: Upon completion of this unit, students should be able to: Understand the steps of the design process Understand the concepts potential and kinetic energy Understand Geometry concepts (radius, diameter, circumference), their relationships...

How I Designed This Step 1: "Imagine Mathematics" I started by imagining how to translate math and its variables into a physical model. I realized that two-directional movement was necessary to create a sine waveform, with these movements connected...

this leads me to some math as to how far on the Y axis I can place my carriage if I want to keep it low profile (save z-axis movement area). This means that I can use about 65% of the Y-axis to place my linear bearing mounts (carriage) and still stay...

Here are the objectives: * Create 3D printed creatures using a ball-shere * Learn basic 3D design skills with Sculptris * Combine clay modeling and CAD in one amazing software * Explore geometry, history, art, or math (depending on your classroom!)...

Of course, an L∞ should be a plain cube, but, beyond this point, my computer takes days generating these geometries running my script. My knowledge about these maths is limited, if you want to learn more about these metrics, go and look at other...

I used the technique already tested in my designs like the math train or the finger skateboard. You can print all parts without support and put the parts together very easy. I recommend to use a small drop of glue to secure the whole assembly in...

I trust you can figure out that maths. :-) --- Support needed! --- The KillaJoule must be printed with support and brim. If the support is difficult to remove, increase the vertical distance between the support and the part (most slicers...

I've updated it a few times since, so here is the current version I am using now. Changes include: - added tapered spacers top & bottom on both parts - this prevents top & bottom artefacts / flaring from interfering with the measurement - measures in...

The original version also had ridiculously fine resolution for the fillets and lettering curves, whereas V2 has sane values for the resolution. Some of My Designs Click an image below (opens in a new tab) or go to my designs page and see them all....
