By 1927 computing began to tickle his fancy and he built a differential analyzer, or a mechanical computer to do all the maths! He would teach at MIT penning texts on circuit design and his work would influence the great Claude Shannon and his...

Then sealant cures in 3-5 days, so the flute becomes mechanically stable. ...How I Designed This I designed it in OpenSCAD The theoretical materials are all found by reference http://flutopedia.com/faq_craft.htm and other references...

I have no background in engineering or mechanical design and my parts may not be 100% perfect. I decided to upload this anyway because I felt that they offered an improvement over what's out there. This project is not complete and revisions will most...

I have 5 paintball guns, that is more my lane).I could get started on a final design, but I want to do more testing.Once the Pressure can be maintained I want to test how long it maintains pressure; a full day at operational pressure is my goal...

So here it is, the new version 2.0 of the table clamp, fully compatible to version 2.0 of the miniature vice.Besides the compatibility rework, I have also streamlined the design a bit, by removing some unnecessary material at the main bar below the...

If you print it upright, you will put all the load on the layer to layer adhesion.I recommend to print the t-nut from PETG, which is something I generally do for all mechanically functional parts. It may work in PLA as well, but that is not...

It is marked "FD" instead of "FL" because it has a mechanism for stopping down the lens, so it will work with FL, FD, and FDn lenses. However, there's a slight trick involved, which is why I've posted <a href="https://youtu.be/MGWO7VkcsCk">this...

A mechanical digital clock with three digit wheels on different axes (X, Y and Z) from each other.Visually crazy but practicalDriven by a single stepper motorAll parts are designed within 180 x 180mmEasy time adjustment by manual (physical)...

Parts have not been oriented correctly, do this in your slicer.I use at least 60% infill on these partsPost-PrintingSanding will probably be needed for themagmomentary andtriggergroup files.Be careful with the wiring for thedovemag andmagmomentary...

......The essential puzzle mechanism is the same, though Nova has an especially striking appearance: mathematically, the assembled Sirius has the shape of the first stellation of the rhombic dodecahedron, while Nova has the shape of the second stellation.

It also requires more metal dowel pins.&nbsp;Other optionsFewer Magnets - While magnets are recommended for reliable movement, it is possible to use fewer magnets in the toggle mechanism by only adding them to one side. If the slider fits tight...

For all areas that take mechanical load I added modifiers and set the infill to 70%. Maybe this wasn't required, but I just wanted to print it once and everything turned out sturdy.</p><p><strong>Files and Scaling</strong><br>The spacers for the...

While I did center my servo horns on the mechanical 'center' of the servo, when I set the value to 90 degrees in the code, the servos were not at center position. I had to adjust these home values to center them. YMMV</p> <p>For those wondering about...

Problem statement:  The MINI's XZ tower does not have a squaring/alignment mechanism, possibly resulting in an X-Y non-90-degree skew.  This skew really matters when printing pieces that have to mate together.This adjuster piece and procedure allows...

If you do, please post a remix! Print instructionsCategory: Mechanical Toys Summary Fun top for making cool patterns using a standard hexagonal wooden pencil. Before you print out the top body, print out the sizing template! This should fit onto the...

(extra screw holes are available if you plan to stack more than 2 rows of drawers or contents of heavier than normal weight.)• Prep the drawer case for installation:• Install GEN2-QL (QuickLock Mechanisms) into the drawer case. These will allow you...

Using a hot knife I cut a slot to let the duct assembly clear the tensioner mechanism. ...It ain't pretty but it works<img class="image_resized" style="width:100%;"...

It's removed by pushing down on the release latch.The stick and buttons use flexures – that is, thin pieces of plastic designed to flex – both as springs, and as mechanical linkages to transmit the inputs to the Joy-Con inside. My original prank...

I have made a totally new mechanism design that overcomes this. I’ll post it soon in a robotic hand object. #### Conception #### I have tried to design a universal ball joint that is - print in place - lockable This stickman has 23 ball...

Those tubes were designed to hold American-style poker chips (casino cheques) in standard 39mm diameter. The end caps lock with a screw mechanism that will lock with a little "click". They have a pseudo "seal" that reaches about 1mm into the tube on...

It won't walk well due to the floppiness of crankpins, but the mechanism works, and it was a great printing challenge. The end result is an excellent sculpture. See the "Instructions" tab for details. All parts have been scaled down to 90% to fit...

Six plastite screws are used to attach the mechanism to that box. Wiring In my wiring photo you'll see a lot of stuff, most of it is not used for the functionality described (eg, pointing at space ships). I wanted to obtain data from the internet,...

The Z-Box attaches at the base of the z-axis and replaces the lid of the stock electronics board enclosure using the same mechanism for attachment.&nbsp;See here for 4B versionThe Z-Box relieves strain by rerouting the MINI's cables in a more...

level, maybe lower down if they don't have such powerful computer, no reason for any problems with it being created because I have given instructions properly even though Im a large complicated thing myself with so many internal working mechanisms...

I also wanted to keep it compact while amplifying the mechanical swing to increase error tolerance and require no adjustments. So, I went with dual pivot, but that requires bearings for reliability. However, many users already have them from the...

The hand crank, when turned causes the center carriage mechanism to rotate around a stationary cone. The motion of the carriage in combination with the stationary cone causes the winding spindle to rotate about its axis. The winding spindle completes...

&nbsp;The locking mechanism uses a hidden barrel cam to move a pin up and down. I tried 10 or so various locking methods before I settled on the barrel cam.</p><p>Instructions:</p><p>1. Slice and print the top and bottom of the egg, titled...

Plus, the length of the turning shaft is usually not a constraint. Post-Printing SIM card tool is a perfect fit to temporarily secure top gear Using the mechanical advantage of the gearbox to thread itself onto the pot. If the fit is too tight, you...

It's loosely based on the mechanics of the Printrbot, with the X axis of the Prusa Mendel. I basically took what I liked from both RepRaps and redesigned them to fit my needs and to use a 4 start 8mm leadscrew. Story behind the printer: Ever since...
