So you examine the mechanism that should trap every particle in the filter, only to discover that they probably tested everything except for that silly flap. Turns out it never really closes as intended, and the resistance of the mesh being higher...

With MGN linear rails on all axis and an extremely rigid structure, this kit is mechanically elegant and tough at the same time. A Modder's Paradise -Designed from the ground up with the modder in mind, the V-Cast is an open platform with endless...

The toy features a functional dual-action trigger mechanism. The toy requires 3 common steel springs, two elastic rubber bands, 17 M2 hex socket cap screws, 7 M2 nuts, and 4 M2 washers. For ammo, I use common plastic strip caps. More detail is...

Introduction This rubber band gun is based on the clever trigger mechanism used in “M1911 Rubber band gun” (thing: 3053501) and “MINI rubber band pistol” (thing: 2740883). The goal was to make a rubber band gun with the same attributes as the 1860...

You will probably also need to print two nubs, and use something like a mechanical pencil spring.Ideally if you need to replace the nubs, though, you'd use a 4mm graphite rod and shape it like one of the existing nubs. Easiest way is chuck it up in a...

The mounts have been designed with a Kinematic mechanism based on the Maxwell principle. As there are 3 mounting points, these are expected to be in the following locations on the bed: 1. Front left mount: 10mm from left edge of bed, 10mm from...

Human touch perception begins with sensory receptors in the skin that detect mechanical pressure, vibrations, and other stimuli. It then passes through the nervous system, where it is interpreted by the brain as a sensation of touch or texture. The...

I have then used the reduced mechanical requirements that come with the smaller size, to make it very simple and very cheap to reproduce. At that size, very good accuracy can be achieved even without metal linear ball bearings.</p><p>And let's face...

If some sort of mechanical fixture is desired for reinforcement, there are two options. a. For bolts, poke a hole through the belt from the inside using the witness holes. Either use a drill bit, or a hot needle, soldering iron, etc. Fasten the...

PLA), leading to mechanical failure of the turbine at high RPM. Limit the runs to a few seconds. - Wear safety glasses and gloves while operating. - The operator of this turbine (i.e. you) is responsible for the safety of bystanders. - Don't...

I have found out of experience any many prototypes with my HEVO that this little mechanical indulgence is well worth it in terms of longevity.Printing1.All parts print without supports. There are some sacrificial layers across some holes to help...

The entire sieving apparatus assistant In order to maintain the quality of the product, it is crucial to use the whole sieving mechanism efficiently. This ensures that any unwanted particles are separated from the desired output. Thus, using the...

... at .15mm layer height.</p> <p>Here's a video of the toy with some details. The video has a lot of assembly photos at the end. If I missed a file or some other detail, let me know and I'll try to fix it. Good luck, Rick Category: Mechanical Toys

In terms of mechanics and electronics, this design uses the cheap 1/10 scale ones. We could consider that the 3D printed gears would be 1/8, as they use Mod1 teeth size, normally related to 1/8 rc cars. So if you are looking for a sourced motor...

Of course it's possible to engineer the drive mechanism differently, and I encourage anyone to do that if you desire a different type of drive! This was the quickest way for me to get it running. My idea right now to make it dual axle drive is to...

Please to be careful when using, you are pulling away from the blade and I have never hurt myself using it but be careful nonetheless, you can optionally wrap the unused edge in a few layers of tape to make it extra safe.&nbsp;In terms of the quick...

This is a mechanical dispenser for example for fetilizer but you can put in this whatever you want.&nbsp;&nbsp;things you need apart from the printed parts :-2x &nbsp;M3x20 screws (you can find these in the spare bag if you have a Prusa)-2x...

I used small jewelers files and plenty of patience to perform this step.Assemble the Staircase.To assemble the staircase, I performed the following steps:• Slid "Staircase.stl" up through the bottom of "Base.stl", pressing it upward until the...

They tend to rattle a bit though. six size 608 ball bearings Brass Inserts (Melt-in): M3 long and short for various mount points, M4 x7 for camera slider Screws M3, M4, M5x20 If you use hall sensors: a small wood screw with flat head (magnetic, as...

I have removed the mechanical Z endstop on my V0.1 and use the IR probe as an endstop and it has greatly simplified my homing sequence. There are additional x-frame pieces that allow mounting the Beacon3D probe, Euclid or Biqu MicroProbe for a V2.4,...

An adjustable lampshade which acts as a mechanical dimmer. Designed around the IKEA HEMMA cord set but it should work on any socket with the same diameter (~40mm including the threads). If you want to try another socket, print the threadtest.stl...

I believe it would be the best suited for the job, given armament and size for such large mechanisms needed technology wise to bridge the gap. And most importantly ROOM. This Nova has seen EXTENSIVE hollowing and rebuilding to make the necessary...

This polyhedral mechanical puzzle was invented in 1971 by Naoki Yoshimoto, who discovered that two star-shaped rhombic dodecahedrons could be assembled into a cube. These two dodecahedrons allow the cube to be divided into two equal parts. ...

FeaturesFully parametric round or n-gonal container.&nbsp;Walls and cover top can be either solid, with square holes, or with straight triangle holes.Can add an inner "brim" or "overhang", which in turn allows the use of a flexible sealing...

One is to purchase a correctly sized approximately 6mm x 100mm spring and fit it between the pin and the slide bottom to have a fully encased spring mechanism. The pin would then get super glued in place. After making a few of these though, I think...
