For instance instead of symbols that must be matched here, a more difficult puzzle could be created by making the symbols into numbers so the user must do math to solve the puzzle. The symbols could also be changed to arrows pointing towards more...

I had to do the math backwards to figure out what would fit when the doll is printed at 100%, so these are technically untested but I'm pretty sure its the right size. Headcap: Unchanged from bahboh's Polaris, it does require some sanding to fit,...

Thingiversity Math Challenge: Build A Castle. - Build Egypt, build Rome, or build your own kingdom! This set of objects is a must-print if you plan on heading to the beach anytime soon. It comprises three unique castle molds, an adjustable...

I then crunched some numbers on WinISD for the 5 1/4" subwoofer with an 8" passive radiator, and the math checked out (really well actually). The goal was to get the whole thing printed, in one piece, on an Ender 3, including supports, bracing,...

Do the math beforehand and know your components' dimensions, some of these models are large and can take more than 24 hours to print (based on specific settings). ### Small - 18mm TopHat Fan size: 2x120mm Fan height: 15mm _Scroll to the bottom to...

* Consider Panel gaps as a single edge rather than both to simplify math * Tapered screwless feet tips to make it easier to fit box halves together Update 2018-07-27 * Adjusted filet size around square holes by the cutout margin to achieve the...

Do the math beforehand and know your components dimensions, some of these models are large and can take more than 24 hours to print (based on specific settings). ### Medium - 28mm TopHat Fan size: 2x120mm Fan height: 25mm _Scroll down to see other...

In case you need to compare these settings or use them in a numerical way later on (like performing math), it might be wise to convert all the numerical values into actual numbers. Here's how to do this with Python's `float()` and `int()`...

There are other similar tests available and I've tried a few but they are often quite big and wasteful and take a long time to print while testing things you don't really need to test in order to dial in your printer. For this test the overhangs...

You can scaffold the math requirements to meet the needs of your students. Having students explore the cost of materials ahead of printing helps them have realistic expectations of what they are allowed to make in class. I typically limit students...

- Using the information and math found on the MatterHackers link, set the 'Steps per mm' value. Most people never do this (myself included when I first built my printer) and it is necessary for reliable prints. Troubleshooting / Items I discovered...

And yes, you can store your 3D tiles too!) This was all possible due to hard work and testing using mockups and other math techniques in the process. The goal was to be able to completely close the box keeping the lid safe and aligned with the bottom...

A measurement of the amount removed using a micrometer or calipers and a little math determines a LayerStack score. Procedure: Slice and print layerstack_cube.stl. Slicer settings are given below.</li> <li>Measure and write down the distance across...

This gives more possibilities to match the hemisphere to other objects.UsageTo use this, simply put this file in the directory where you keep .scad files, and include this line in your other .scad files:use &lt;geodesic_hemisphere.scad&gt;Use it...

Don't mind the math; it's written for a layperson. Instead of a linear probability distribution of the d20 advantage/disadvantage mechanic, the loaded dice appear to have a curved probability distribution. It is still possible to roll a 1 with the...

Note that there's no math behind this design, I just used elliptical curves and measurements that looked cool. Does it actually increase airflow? No idea, but it looks really cool. Also, since I drew one support leg and then patterned it, I...

... etc. Step 7: Present to your assigned teacher. Duration of Lesson About 7 - 10 class periods (45 minutes each) Rubric and Assessment STANDARDS 6th Grade Math: Solve real-world and mathematical problems involving area, surface area, and volume.

In order to keep the math simple, transducer placement is done assuming you want 44000KHZ, so that gets you ~4.5mm. Increasing voltage increases the density of objects you can levitate. ## Parts list For a BigLev, please print: * 2 BigLev-half.stl...

The motor have two options for mounting, my original thought was that it would give different gear ratio (you can mount it to either the big gear (50) or the small gear (25)), but due to reality (and math) it did not. Oh, If you take the choice...

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...

Make sure to not allow a loose fit, either.Basic ModelInstall the two M3x6x4.2-3.6 threaded inserts and quadratic nuts to the BearingSeat; the threaded inserts will later accept the two M3x12 flat-head bolts to attach the toothed belt:If the optional...

On 01/25/17, the "math" was corrected and notes clarified. On 01/27/17, the treads were corrected to match original design size with new supports to print right side up. On 02/2/17, a re-thought occurred on why have supports/tabs etc. Why print...

If you have short fingers, you might want to chop it off at 60 or 75 - I just liked the math of being able to hold 20 per tube. There's a "window" slot in the side so you can see what's in each tube if you color-code yours. The window can also help...

The objectives of creating Juno are: * Follow instructions to create a functional Juno * Demonstrate understanding of circuits to power LEDs and motors * Describe the functions in the provided Arduino code * Creative design to personalize each Juno...

V2.1 After trying to build it I found out my maths was wrong. Wheel arches were preventing the wheels moving freely. I also found that the top parts of the motor mounts were snapping, glad I added the zip tie holes now.... if they snap off during...

* Math: Students apply mathematical concepts to real-world problems and applications. Skills Learned By working on PINBALL, students will develop: * Teamwork and collaboration skills * Spatial awareness and problem-solving abilities * Programming...

How I Designed This I found it challenging to create exactly the shapes I needed using any of the pre-built routines in OpenSCAD, so I broke out some vector math and generated each thread as a custom polyhedron. The best way I could think of to...

Subjects: It can be used in science, math, and programming classes where students calculate and program their Sphero while learning trial and error. Activity: A teacher can challenge their students to program their Sphero to draw a shape or...
