New version here https://www.printables.com/model/575252-stone-arch-puzzle-blocks I print on the back of the bridge segments because that gives the blocks a little texture so they don't slide as much. Pieces fit together seamlessly, the…
The demonstrator of cog wheel 02 is a result of engineering done step by step from desing to production. Cog 20. Modul 2,5. Ra=da=55mm. Axis distance 50mm.
This design is based on a card stock model by J.L. Snider, Oberlin College, 1992. It is intended for educational outreach & demonstrates the Sun's daily motion & position above the horizon for northern (or southern) latitude observers for…
This toy's original concept was to show kids how gears work with a hands-on demonstration but it also turns out to be fun to play with. The gear train consists of 7 stages. Each stage has both a larger 42 tooth gear and a smaller 14 tooth…
Aerozono Space Technologies BS-1 Fully printable PocketQube Tech Demonstrator Two Award winning design at the Latin American Space Challenge (Award For Innovation and 1st Place in PocketQube ) This is our Webpage . Preliminary Design…
Mount for socket AM4 or AM5 CPUs that combined with acrylic glass sheet shows you the spread of your thermal paste using the same or similar pressure as your cooler mount. Works with the stock mount screws that came with your motherboard.
This model can be used to get an impression of the physical term “pressure”. Pressure is defined as force per area and with this model the force applied by a weight can be distributed via 1×1, 5×5, 10×10 or 20×20 pins. Put the model on…
Add an hour dial to your Solar Motion & Position Demonstrator to show how time is related to the position of the sun in the sky. The original demonstrator is available from here: Solar Motion & Position Demonstrator by 3DMason | Download…
John Logie Baird’s pioneering design for television utilised a mechanical Nipkow disk and analogue electronics to encode and decode video signals. This demonstrator highlights a key effect of the spinning Nipkow disk: when rotating at a…
Mount for socket 1700 CPU that combined with acrylic glass sheet shows you the spread of your thermal paste using the same or similar pressure as your cooler mount. It is compatible with screws and backplate from Noctua mounting kit , but…
A mostly, yet not fully, working attempt at recreating a manual valve from the fischertechnik 80ies pneumatics program . Note: the photos show an earlier version, I added a third fitting and tweaked a number of internal measures in the…
I wanted to show capabilities and also a visual support to introduce heat insert for my team of designers. I made this simple demonstrator to show how the inserts look like and show how strong they can be.
Description: This "Filling Demonstrator" is a set of small 3D-printed cards designed to help you visualize and compare different infill patterns used in 3D printing. Each card showcases a unique infill pattern, clearly labeled, with its…
4π Spin-½ Rotation Symmetry Demonstration – A Mechanical Model In our everyday world, a thing that rotates one full circle — corresponding to the number 2π, marking the circumference of the unit circle — is back to where it started. But…
Crystals show birefringence, also known as "double refraction". In very simple terms, crystals (with some exceptions) have two indices of refraction. This leads to one light ray being slowed down and color-shifted compared to another…
This is a Geneva Wheel Mechanism set up for 8 stops. It will need (2) M3x.5 @ 10mm screws, for which I highly recommend pre-tapping the holes in the base. They're modelled threaded, but threads that fine often need a little help. This…
Info This is a case or holder for the Globe Demonstrator. A cool gadget by CDA GmbH using light interference to create images of star field, turning globes, the moon and their logo. You can find a demonstration at…
An object topples over when its center of gravity (or center of mass) moves beyond its base of support. This process can be understood using concepts from physics, particularly equilibrium and stability. Here’s how and why it happens: ###…
This is a simple dual-slide movement demonstrator. This is essentially the same motion the cylinders in a V-configuration, four-stroke engine make. To build, you will need to print: (1) Base, (1) Thumbwheel, (2) Conrods, (2) Slides, and…
I would like to thank @3dMason for all the good work, well done.
This is a Geneva Wheel Mechanism set up for 4 stops. It will need (2) M3x.5 @ 10mm screws, for which I highly recommend pre-tapping the holes in the base. They're modelled threaded, but threads that fine often need a little help. This…
This is essentially a re-mix of a Crank Mechanism by Adam, but with a few modifications.
This is a simple Parallel movement demonstrator. This is one of several solutions to the problem of steering and parallel control. It will need (3) M3x.5 @ 8mm screws, for which I highly recommend pre-tapping the holes in the base.…
Turn a letter into cipher with your own hands, the way the Lorenz machine did it: five wheels of pins, a press of a lever, and a window that shows you the answer. What it is This is a simplified teaching model of the Lorenz SZ42 cipher…
Press a lever, watch the rotors step, and follow a letter through the wiring with your finger. This is a rotor cipher you can see inside. What it is This is a simplified teaching model of a three rotor cipher machine in the style of the…
