Parts: base handle stone x 3 pin x 3 Assembly: put pins in stones put stones into their tracks put handle on pins check if everything moves freely connect handle with pins, you can use glue, I used a soldering iron set to 120 ° C (for…
Turn the crank and the glides move back and forth in their channels, never colliding, but also doing nothing. This fidget is based on the Trammel of Archimedes , which is a mechanism that traces the shape of an ellipse (which can easily…
Detailed Description: This rod compass is a practical tool for marking large circles on wood, metal, or plastic. It clamps onto a profile such as a wooden strip or a spirit level and allows diameters from approx. 85 mm up to over 4000 mm…
This was created using Fusion360 and it's rendering feature. On the top of the “Sliders” are holes to put M4 screws (with washers) into. They are there to hold down the “Handle”, so that ist doesn't fall of when in use. They have a…
5/24/2018 I changed the files a little to make them more flexible in scaling to a 75% scale. I also added some extra M8 & M6 Nuts with 2 different tolerances in case my default .4mm tolerance is too tight for you. The full size version…
This is an updated version of the trammel based on suggestions I received from Bassposauist . It adds a scale and is a little more compact. Another suggestion was to use the knob designed by ItsAzuurfor_ for a M4 hex head bolt…
I set out to make a yardstick adjustable trammel set using as many parts 3d printed as possible. I hope to make another version using some standard hardware, but this one only requires 1 nail, with the rest all printed. The set consists…
This beam compass (trammel) is used to scribe a circle or arc, by using a sharpened point at one end and a lead pencil at the other. The radius can be adjusted by sliding the pencil holder across the tool’s beam, and locking it in place…
The "Trammel of Archimedes" is a mechanical device that creates an elliptical shape using rotating rods. It's named after Archimedes, though his direct involvement is debated. It demonstrates how an ellipse is formed by maintaining a…
An Archimedes trammel, which does literally nothing but looks cool I guess. Also fun to play around with. Makes a good desk toy. Print Settings Rafts: No Supports: Yes Resolution: 0.2 mm Infill: 15% Filament: SUNLU PLA+ Black and Yellow…
I enhanced the " Trammel of Archimedes " by Madox to a three-way-version to realize the same functionality (nothing) with a bit more effort. It's drawn from scratch too but I tried to keep his design. The slider is unmodified and uploaded…
Mechanical motion demonstration model This model demonstrates a Trammel of Archimedes with three sliders , a classical kinematic mechanism used to generate elliptical motion using constrained linear movement. By rotating the central…
Print in place using supports as “touching buildplate only” to support the handle. Use thick walls of 1.6mm.
Insert sliders into the horizontal slots on the body. slide the squares into the vertical slots on the ends of the body. put the arm on the ends of the siders. add the clips on the top of the arm on the slider.
My take on the Trammel of Archimedes as a simple little fidget toy. I designed it to be as minimal and straightforward as possible, with an easy click-in assembly and a decorative pattern to give it a bit more character. It prints well in…
None of the parts require support and should be done in around 3 hours but can be sized up and down. Should be smooth but if needed you can sand down the blocks. Works great and does not jam.
I saw this model made in wood many years ago. I couldn't find it online, and frankly, I couldn't think of what to call it. If anyone knows the original designer, please let me know and I will give him credit. Anyway, I remembered the…
Explore the genius of Archimedes with our 3D model of the Trammel of Archimedes—an intricately crafted digital marvel. Witness its dynamic geometric movements and elegant precision as it traces captivating curves. Ideal for mathematics,…
The modified pivot piece can be printed without supports and attached to the cone with a short piece of 1/8" dowel. I used PLA, but any filament should work. As in the original, you can use a ruler that is the proper thickness or, a strip…
Designed it after watching some YouTube videos while at uni. I was curious how easy it would be to model in CAD, and after some messing around came up with this, it is a flawed design which can fall apart quite easily and has not been…
To build it you need: one M6 x 20mm grub screw but you can also use a normal M6 screw and make it pointy with a drill and some sandpaper one O ring (14 x 2.5mm or 17 x 2.5mm) to hold the pen (or a other rubber band) one stick 10mm x 20mm…
PLA / 0.3-mm layers/15% gyroid infill/2 perimeters Recommend using brims for Pins & Axel and using organic supports for Travelers Assembly per graphics
I honestly have no idea what this should be called. I know it's been done before and I know it's nothing new. I just wanted to finally make one....whatever it is. Plus it's pretty satisfying once you make it, put it together and make a…
I made the base taller by 10mm so you can grip it better without your fingers getting in the way of operation
Use this a point to level the motors on any drone with round arms. I made it for the X500v2 but it will work on anything.
Simple Nothing Grinder or Trammel of Archimedes Was designed in FreeCAD as practice with “real” cad software MAKE SURE to orientate the “peg” so the it’s not so akward, probably a mistake in how I designed it in freeCAD, sorry.
This is a trammel of archimArchimedesedes, or do-nothing machine, or BS Grinder. It can be printed with removable pins or with solid pins that you insert through the handle and glue into the piston rods, just make sure you leave enough…
Design Concept This model appears to be inspired by the Archimedes' mechanism for drawing an ellipse. It's designed in a simplified way to focus on the mechanical functionality. At the end of the mechanism, there is an option to attach a…
Trammel of Archimedes — a "do-nothing machine." WHAT IT IS This is a completely useless, completely satisfying desk fidget. Crank the knob and the arm sweeps around, tracing a perfect ellipse over a groove engraved in the base. It does…
A way to pass some time. PLA/0.3 mm layers/3 perimeters/15% gyroid infill Note: The knob on the handle will spin once freed up after printing. If necessary, protect the know with tape or paper towel and carefully use plyers to make rotate.
I was looking at mechanical devices to apply to my Tectonic game and I like the function of the Trammel of Archimedes (also called an Ellipsograph). These are often posted as "Do Nothing Machines", but it is a misnomer. It's a device to…

This is a 3D printed rendition of woodworking trammel that can draw circles up to 5 3/4" (about 140mm). Original wooden version of this can be found here https://www.pinterest.com/pin/229965124709474743/ You would also need a 1/4" by 2"…

Trammel points for larger circles. Limited only by the steel rule you use. I found I needed to more frequently draw and cut out larger circles and arcs than I have templates for and which are too large for my drawing compasses. The radius…
