Print instructionsCategory: Mechanical Toys Summary My take on the tri-spinner fidget toy. You will need 4 standard skateboard bearings, 22mm OD / 8mm ID / 7mm Thick I prefer the Thicker Spinner Body (this is what is in the picture) Print 2 Center...

I noticed this with the first heavy prototype. I then redesigned the gears set, enlarging them to accommodate a bigger and more powerful spring. Initially, both for greater smoothness and to improve mechanical tolerances, I created a model that...

You should probably use a drill press for this since it requires more accuracy.On my quest to print at very high speeds on my Ender 3 Pro, I noticed some room for improvement in the Y axis mechanics.The V rollers were inconsistent and unreliable, the...

(Exploded shortly afterwards, next to my head haha!) I have since shrank it to fit but I need to design a screw mechanism as glueing it together is not viable under the stress it's put against. I took the design of the bazooka rockets mentioned...

That's why I wanted to make a model of a Sharpie marker that was not only accurate enough to mechanically fit well with the standard Sharpie Fine Point, but also be easily workable to assist in the modding process.MeasuringMaking an accurate model of...

### The Solution: This mechanical device enables the user of night vision devices to select a desired aperture thus controlling the depth of field and allowing the user to focus on a wider range of subject distances. This device also allows the user...

On the other hand, for those who are interested to print and test the device, see the printer’s note and the components list, and to use the device attach the tag an object that want to track.Then, use the tracker to find the object, and to create...

When he burps, out of his mouth comes out a fire like a small mechanical dragon. Small because its height is only 168. However, it is made of a very durable alloy that gives it the ability to survive after more than one explosion. In a critical...

It is also worth noting that the wires inside the heating table should not be soldered, but installed on a mounting rail with a screw connection of the wires, and the wires should be laid in heat-insulating tubes, and each should be isolated from...

...I spent many hours looking at videos and images that I found on the web of the original watch. Similar to the Gyrotourbillon and the Triple Axis, I tried to make the model an accurate (scaled up) version of the original Furious tourbillon mechanism.

This is a 7mm thick spinner. Print instructionsCategory: Mechanical Toys Summary My take on the tri-spinner fidget toy. You will need 4 standard skateboard bearings, 22mm OD / 8mm ID / 7mm Thick I prefer the Thicker Spinner Body (this is what is in...

The buttons are a very snug fit, mainly because they need to hold up to mechanical pressure when you're adjusting the brightness.Remove the components and program the Trinket using the bar-lamp.ino code. Note: At this point, I tested the dimmer...

Description:This is a "stopple" for the 50 mm hole in the LM's top plate that fulfills three tasks:Stuff the hole, so hot air is kept inside (if using a printer enclosure)Integrate a swivel-mounted filament detectorIntegrate a temp sensor to measure...

To avoid the microswitch issues, I decided to integrate a standard mechanical filament sensor. These cheap sensors are simple and reliable and also work with soft filament (to a degree). Yet there's the chance that some very soft TPU can't be pushed...

Tolerences of the locking mechanism might be tighter depending on printing speed and quality of the filament if printed with a 0.6mm nozzle. Multiple Extruder Printers: For printers with the ability to print multiple materials at the same time you...

This Thing is a replacement for the main gearbox body for the trunk lid pull-down assembly in my 1992 Cadillac deVille, reverse-engineered from the original part (as mine broke in several places, due to age and excessive mechanical stress). It...

The Boom 3 from Logitech/Ultimate Ears uses a proprietary charging mechanism on the bottom. A dock from Logitech/Ultimate Ears is available. It contains one LED (to show the charging status) and a micro USB connector. The “magic” behind the charger...

Used to collimate the scope.The following additional parts are required:4" Schedule 40 PVC pipe, 6-7/8" longM5 X 40mm hex-head bolt and nut: Used to focus the scope by moving the primary mirror.0.6 X 7 X 30mm compression spring: Moves the objective...

There is even a place to store the key.A spacer is used under the pall on the inside of the locking mechanism to accommodate the thickness of the door handle.LED Strip HoldersIncluded are 3 sets of LED strip mounts. Four horizontal along the top...

Using this binding mechanism, an antibody can tell other parts of the immune system to remove the foreign microbe or virus. To have protective immunity, the body needs to produce a certain type of antibody, called a neutralizing antibody, which...

The mechanism may be a little stiff at first but should loosen up over time. ...A little bit of silicon lubricant can also be used on the dovetail joints to make it work more smoothly.</p><figure class="image image_resized" style="width:81.4%;"><img...

It will require a lot of modification, mechanical ingenuity, plenty of airsoft teching experience and general DIY'ing patience. The modifications necessary to turn the TR16 into a No Time To Explain cannot be reversed unless you are willing to buy a...

... After the assembly, the model will stand 250mm tall, 150mm wide, and 139mm deep. Note: Click HERE to watch the YouTube assembly video of the articulation mechanism. Buy MWO War Hammer builds by clicking the green ‘Buy’ button. Proceed to checkout.

7 - Assemble and install the dust filter - cut the sponge into pieces that fit the dust filter - clamp it onto the filament before the input ptfe tube inside the dry-box 8 - Assemble and install the Filament Runout Sensor - see...

The learning mechanism would be possible only with a feedback method, like the ultrasonic or infrared sensor. For the power consumption a Hall effect current sensor could be fine. Sinusoidal The only sequence I tested is a sinusoidal distribution. By...

This is especially important for the lock-in mechanism of the lid. I've included a test model which you can print to check accuracy.</p><p>If you find the lid doesn't slide easily (printed too wide) or it doesn't really click into position (printed...

Of course you can use it with every other Firmware that supports this kind of switching mechanism. # Why? The intention was to build an extruder that is easy to build, low-cost and doesn´t add much weight to the printhead. I don´t print with...
