A second gear has been added to stabilize the shat gears and make the forward/revers rotation smother. 1.75 filament is use as guide pins to align the halves while gluing it together. 1.75 filament should be inserted in the 2 holes to secure the...

Modeled in OnShape. I attached a small motor to make it spin. A small pin (cut from a toothpick or something similar) should be inserted to hold the middle gear in the tube. If you appreciate my designs and would like to support my work, consider...

A turbofan that spins in opposite directions is called a counter-rotating turbofan. ...This engine design utilizes two fan sections which rotate in opposing directions to provide improved efficiency and reduced noise levels compared to traditional...

A mesmerizing display can be seen at https://www.youtube.com/watch?v=5aCxEEicy8I&feature=youtu.be, where the hypnotic movement of counter-rotating hypercubes creates an otherworldly ambiance. ...For those interested in exploring the underlying code, a...

This is a contra-rotating mechanism designed to make propellers rotate in opposite directions like those found on the TU-95. Just place the models flat on the bed and assembly should come easily, requiring no additional support. ... The "drive"...

This setup should not be confused with counter-rotating propellers, which involve two separate propellers mounted in different locations and rotating in opposite directions, such as those found on either side of an aircraft's wing. For more...

This is a simple demonstration of how a contra-rotating propeller works. DXF file is included if you want to edit it in any way. Once the model is together, you should glue the necessary parts to each-other. ...Glue should connect prop 1 and gear 2,...

This is supposed to look like a spinning propeller. I used a thin wash of black for the inside. The outside ring is yellow for the yellow on the tip of the blades. ... I'll add a file so you can customize the size of the hole.

You've managed to print a planetary gearbox with precision sufficient for overdrive operations, scaled up to 200%, then you're good to attach this part: You're ready! ... December 29, 2015 - The changes I made helped resolve some path generation issues...

Diameter is precisely six hundred and sixty millimeters.

A clever '1 dice' counter system, mounted on a sturdy stand with ample space to display the card triggering the counter. This handy tool allows users to keep track of turns for themselves or others. Simply rotate the arrow on the dice holder to...

Here is the rewritten text: A spinning counter displays a "1 dice" figure, mounted on a stand with space to hold the card triggering the counter. It's perfect for tracking turns - whether it's for yourself or others. Simply turn the arrow of the dice...

For more information, please visit: https://youtu.be/dCCo4gIuark The concept of counter-rotating propellers aims to eliminate the torque generated by just one propeller. ...This could be an intriguing upgrade for the Toypedo or similar projects like...

... The idea behind counter-rotating propellers is to eliminate the torque of a single propeller. ...This could be an intriguing enhancement for the Toypedo (http://www.thingiverse.com/thing:932180) or other similar projects.

The contra rotating propellers minimize the torpedo's spin, making it travel farther and more efficiently. A pin (like part of a toothpick) is required to hold the middle gear in the casing. A small motor can fit inside, along with small batteries. A...

With a gear reduction of 1:3.333 (output : input) the following are the bevels from a previously uploaded high speed propeller gearbox. ...The bevel gears are from locked differential of 1/16 Brushless 4WD Mini Rally car

I'm designing a high-speed bevel gearbox with a gear reduction ratio of 3.333:1, perfect for drones. As part of this project, I've also created a custom propeller design that will be shared later. ...The bevel gears used in my concept are sourced from a...

... my take on a high-speed bevel gearbox for use in drones. ...I've also come up with a self-designed concept propeller that will be shared later. ...The bevel gears utilized are from the locked differential of a 1/16 scale Brushless 4WD Mini Rally car.

Additionally, two propellers are needed, one positive and one negative, both D44For4mm, sourced from https://www.aliexpress.com/item/32527058344.html?spm=a2g0s.9042311.0.0.76474c4dW5NDYO. ...Lastly, acquire two of these items:...

It's specifically designed to match an 8" or 9" x 6-7" 3-bladed counter-rotating propeller. Version 1 of the base features a negative offset, with the bottom edge of the spinner sitting "below" the prop adapter by .3125". Version 2 has a normal...
