Kids can learn which fractions are equal, for example 2 1/8 are equal to 1/4 by stacking the 1/8 pieces on top of the 1/4 peace. The more advanced can add 1/4 and 1/8 by putting them onto the plate and counting the sections of the plate.

The most advanced calculation that can be done is something like 1/2+1/6=2/3 by putting the corresponding fractions onto the 3/3 plate.

I'm going to call this an "educational" brushless motor because last time I checked PLA isn't ferrous (I can haz magnetic domains?), the rotor is using flat magnets (I can haz more flux?), and the rotor should be 1 angstrom away from the stator but... its not.

You can print all these parts without supports.

You slip it onto a 10mm square wooden rod and stick a 3mm fibreglass or carbon fibre rod in it. Use to pull a string wrapped round a car axle

Simple small laser cuttable bag tag for giveaways. Actually developed as a way for students to mark up a 10mm border on their sheets. make these and people will flock to get one

Simple protractor, highly accurate, for cutting out of thin plastic with a laser

Marble Run Ramp Jump

A chicken shaped catapult cut from an A4 piece of 3mm acrylic or plywood. Developed by myself AJ Booker, for my client the Nottingham eLearning Centre nelc.net it is one of 8 FREE projects I designed and developed on the notadesktidy.org website I set up for them. Each includes 3D model files, a user manual, sample files, images, introductory films, worksheets and powerpoint presentations. The catapullet includes an extra presentation where I narrate the steos in designing and prototyping the catapullet

A demo piece shown on the youtube film youtube.com/watch?v=xLLYc-8VWsY where I designed and printed something useful and durable from scratch in under 15 minutes. I will be publishing other samples of these 15 minute projects over the following week as films and files

HUGO! is the name of this robot which is designed to fight cruel and brutal bullies.
He has awesome looking ribs that doesn't just look scary, but it also sprays an anti-bully gas which make all bullies harmless and kind.
The gas is stored in his backpack made of carbon-fiber.
HUGO! is part of the Science, Technology, Engineering & Mathematics (STEM) Network conducted by Momodou S. Ceesay to encourage young pupils to pursue STEM careers.

This is a stand designed to hold 50mm diameter lenses for experiments with optics that I designed for my friend Hans who is a teacher. The stand can be clipped onto the edge of a meter stick so that measurements between lenses can easily be made while they stay aligned. The stands can double as feet to support the meter stick, or even holders of a light source such as a flashlight or laser. The design even accommodates all thicknesses in a standard pack of lenses such as this one sold on Amazon.com: amazon.com/gp/product/B00657LW8G?ie=UTF8&camp=213733&creative=393177&creativeASIN=B00657LW8G&linkCode=shr&tag=theplamik-20&qid=1360550742&sr=8-1&keywords=lens+set

This is a protein model that can be assembled (polymerized) in an analogy to what happens inside living cells.

Actin is a protein involved in maintaining a cell's shape, as part of what's called the cytoskeleton. Actin exists as monomers, but certain conditions (like the actions other proteins, or the presence of certain salts) cause the monomers to stick together and create these long, helical filaments.

Replacement center arm for the Hexapod
This is design requires the horn be glued in. Server horn designed around: sparkfun.com/products/9065

Design found here: thingiverse.com/thing:34796.

Presented worm gear reducer with module 1.5 and 60x10 (6:1) teeth on driven gear and minimalistic frame that hold all details together. Also included motor adapter that I used to connect motor to worm part. All details connected using M4 bolts and nuts.

Reductor that done from identical gears 1:4 each (uniform) and can be setup with as many gears in sequence as you need (scalable) to get ratio and torque that you need.
On images reductor done from 4 gears and has ration 1:256, but you can easy install more/less gears to each of two reductor axes to have ratio that you need.
There also included fram for gears system with holder for motor.

Finger Splint:

With the supervision of Dr. R. Siderits, I have designed a prototype "finger splint". This project offers a parametric file describing this object. It is intended to demonstrate the practicality and feasibility of “3-D printed medical devices”, and to facilitate Thingiverse design derivatives of the parametric file.

The appropriately stringent oversight for design, production, manufacture, distribution and use of the medical devices is not addressed in this project. This project is for research use only.

Finger splints can come in many shapes and sizes. A finger splint immobilizes a finger or joint after an injury. Countries with restricted economies and open boarders may use this type of “Field Splint” as a convenient and inexpensive temporary stabilization device. This file describes a “Field Splint” that can be scaled on any axis and printed using ABS Plastic. Depending on the platform up to 30-40 splints can be printed in one “Run”. Each of these can be scaled independently.

This approach may offer an opportunity to provide standardized devices for clinics, remote hospitals as well as field first aid posts. The cost for each splint would be less than 2 cents worth of ABS plastic. A single small 3D printer could conceivably print thousands per year. Once the file is downloaded the splint can be scaled on any axis to fit any finger properly. This research project would be used for emergency field “dressing” and stabilization. Any medical dressing should be used only under the supervision of a qualified medical practitioner.

Nurture your kids nature with this DNA building block toy/model set.

The design is based largely on a toy I saw at a store and adapted to create with a 3D printer. You can take it apart and put it back together in different configurations to represent various gene sequences.

The test parts shown were printed with 150 micron layers and 100% infill in PLA and they fit together/over the dowel nicely after a little cleanup with an exacto blade. I only printed one each of the A-T-C-G nucleotides to fit-check because blue and white filament is all I've got right now. If anyone makes one of these with a nice color combo I'd love to see a picture of the real thing.


There's another printable DNA playset that's worth checking out - a really amazing design from emmett: thingiverse.com/thing:17343

Map of the us with completely seperatable states. I was inspired by the Electorial college 3D map that I saw here but wanted more flexibility for state modification. Now I can layer for population or make it a puzzle.

This is the source file for making mechanical boxes out of cardboard and wood.
This project was designed as a teaching tool to teach children basic building techniques, introduce them to simple machines, and give them the opportunity to build their own Automata or Karakuri device that they can take home. These boxes have been used with children ages 3-13. The pictures are the output of 6th grade students building boxes in 45 minutes. Here's a video of their output vimeo.com/50900381

EDIT: Uploaded dodecahedral enzyme from Geobacillus stearothermophilus, 1b5s

This is a complex which forms the catalytic core of the pyruvate dehydrogenase multienzyme. The structure is made of 24 copies of a single protein; three copies make up each vertex of the cube. Pyruvate dehydrogenase is an enormous enzyme that connects the process of glycolysis, by which sugars are broken down, to the process of aerobic respiration.

This enzyme is actually from the bacterium Azotobacter vineladii; the human version of the enzyme forms a dodecahedron. Read more about it here rcsb.org/pdb/101/motm.do?momID=153
