iris shutter mechanism 3d models

...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 may harm the mechanical parts of your printer or the micro switch box or at least the levelings. So, before Auto Home, manually turn the Z axis lead screw (or coupler) with your fingers to left to decrease Z level a few cantimeters (ie 1-2cms).

...There was a mechanical relay on it but I changed it with a PNP mosfet. Because the car relay draws only 500ma of current, any mosfet that can handle 3-5A is enough. I have used IRF4905 lying around. You can see the PNP mosfet connection in pictures.

after mechanical polishing clean the parts, prepare wet cloth; 2. heat the surface with the heat gun or small torch until surface gleams (you can see bubbles if overheated); 3. gently run the wet cloth over the surface to smooth and cool it (move...

Despite it’s freakish looks the folding lever pump mechanism can - with reinforced internals - still prime heavy spring loads; with the max load I’ve tested (read: max I was able to fit inside the sledgefire) being 17 coils of pro-26. This mod isn’t...

As the last step before wiring, remove the Förnuftig filter once to add the two wood screws inside the assembly (they keep the assembly from sagging in the middle, shown in the picture, I accidentally overtightened them a bit). Congratulations,...

IntroductionThis rubber band gun is based on the clever trigger mechanism used in “M1911 Rubber band gun” (https://www.thingiverse.com/thing: 3053501) and “MINI rubber band pistol” (https://www.thingiverse.com/thing:2740883). The goal was to make a...

Finally, tighten the screw. OK, if all mechanics are working as expected, your useless machine should work as expected. You can now close the housing, using the last 5 M3*10 screws.</p> <h3>What does it do?</h3> <p>Basically, the Arduino will cycle...

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...

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...

 For critical mechanical parts like trigger pieces, use as many perimeters as possible, typically 8, and 100% infill.  </p><p>All these designs should be printable on a FDM printer without additional support of any kind (some have support towers...

UPDATE: 20.04.2022adapterplate (new design) for model C&nbsp;Hello, we would like to introduce you to our stealthburner conversion mod.&nbsp;At this time it works only with the klipper Firmware.&nbsp;The use with “Marlin” is planned later and will be...

### 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...

Another change has been an improved tilt belt tensioner pulley mechanism. The two small bearings have been replaced by a small idler pulley and the supporting plastics have been strengthened. **Release 6 of the digital bird firmware:** Release 6...

Secondly, it can be used with other controllers as well ... I installed the drivers TMC 2208, with them the movements are silent. In terms of mechanics, there was also one change, seemingly a trifle, and nevertheless it is very important. The...

To use these mounts: stick one side into the cut out opposite of the spring mechanism let the back part sit on the finger nub protrusion, part of the nub should be sticking out over pull the nub and let the board sit and release tension. The board...

(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...

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...

My finger and thumb got multiple very shallow slices in them before I even realised what was happening (so maybe wear a kitchen rubber glove to install or remove the caseless objective, lol).This objective has a nominal aperture of f/4, which is an...

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 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...

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...

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 can...
