solids of constant width 3d models

This unique turntable lets you suspend your filament securely during printing. ...The uniform shapes enable the spool to rotate smoothly, giving it the same effortless movement as if it were balanced on precision bearings.

the solid will have equal width irrespective of the orientation

When you have at least three of these items and position a plank on top, they will rotate freely just like they are sitting on standard bearings. ...Be certain to adjust the height settings in your slicing software if you plan to use all three...

An unsmoothed Curve of Constant Breadth would have a roundedness of 0 and in the OpenSCAD code/module would be a Reuleaux triangle, a fully smoothed Curve of Constant Breadth has a roundedness of 1 and would be a circle. Breadth (Diameter) =2s+L...

About Constant Breath Solids I came across ‘Curves of Constant Breadth’ in an old book – ‘Riddles In Mathematics: a book of paradoxes’ by Eugene P. Northrop. Northrop introduces the idea of Curves of Constant Breadth by questioning whether a roller...

The surface of perpetual blurriness is split into two sections, allowing for effortless printing without any need for additional support.

This is a 3D printing project I did in order to make it easier to explain solids of revolution in math classes and to allow other people to create their own solids of revolution more easily. Print them out and pass them around in order for people to...

His proud job: constantly clamp those books together so they don't fall.. With his arms outstretched, he clamps your favorite books. One more book? No problem, slide a new book in the middle and he stretches his arms even further. He likes books...

Made of equal volume and with edges slightly rounded for ease, these five Platonic solids are not just visually stunning but also great learning tools. ...My grandson loves them, and I'm happy to see him learn their names and appreciate their beauty.

We endeavored to elucidate the mechanic paradox (a double cone that seemingly reverses direction on the inclined plane) and observe the movement of various rotational solids. The class was divided into five groups of four students each, tasked with...

The confluence of two triangular prism-shaped objects.

A student may be asked a question like "What is the volume of the figure created when y=-x^2+9 is revolved around the y axis?" Knowing that each 'slice' of width dx and height y gives a cross-sectional area that can then be multiplied by 2pi × x (the...

Now there are two of the possible tessalations of all 5 shapes plus some combinations of two and three solids in interesting constellations. I was first been made aware of this fractal fit of the platonic solids in a presentation by the great...

The models presented in my teachings on the Intersection of Solids/Interpenetration serve as valuable tools to illustrate and explain complex concepts.

Following the teacher's explanation of the activity, students will utilize 3D printed solids cut into two pieces, corresponding to the intersection of the plane with a specific angle. ...This will enable them to observe the resulting shape of the...

The included Code can generate new Irregular 5-sided curves (boxes) based on user input and works well with the customizer in 2021.1 version of OpenSCAD An Arbitrary 5-sided curve of constant breadth has two degrees of freedom, expressed as 2 angles...

Unveiled during the warm season of my final year at high school

An unsmoothed Curve of Constant Breadth would have a roundedness of 0 and in the OpenSCAD code/module would be a Reuleaux triangle, a fully smoothed Curve of Constant Breadth has a roundedness of 1 and would be a circle. Breadth (Diameter) =2s+L...

Projection Of Solid Introduction Video Lecture of Projection of Solids Chapter from Engineering Drawing Subject for Civil Engineering Students.It is completely bounded by a surface or surfaces which may be curved or plane. The shape of the solid is...

Lesson Objectives: Provide calculus students with a meaningful model and explanation that demonstrates how area and volume can be approximated by summing parts (thin cross sections of a solid or thin slices of an area), where the thickness dx...

The cube is so much a part of our designing tools, it is easy to forget it is one of the 5 platonic solids.Challenge: Print it as a hollow to save time and material. No brim nor support needed. ...Printed in PLA, but any material will do

The results were adjusted to account for the increased strength of heavier parts, allowing a fair comparison of all specimens tested. This was achieved by dividing the measured ultimate strength by the part's mass. The featured graph showcases the...

To achieve an accurate comparison of results, the measured ultimate strength was divided by the part's mass, compensating for the naturally higher strength of heavier parts. This process enabled fair evaluation across all tested specimens, resulting...
