... tube perfectly. With this setup, the lens stays firmly locked in place for professional-grade shots. You can see photos of the process in action. ...The entire project was produced using my UM2 3D printer, cranked up to its fastest print mode.

To take advantage of the toy camera lens from the Recesky TLR, but having the opportunity the get a proper exposure, I made this adapter that fits a helicoid extension tube (Pentax K). The lens barrel is locked when used properly. See photos. ...I...

There are adapters for Leica L-mount helicoid adapters, M42 12mm-17mm and M42 17mm-31mm adapters. They have been tested on Sony E mount (usung a slim M42 adapter to mount the helicoids) but as they go a bit beyond infinity they may work on systems...

3D graph of a helicoid.

This adapter features interchangeable lens mounts with built-in helicoid focusing, ideal for vintage M39 enlarger lenses. To achieve infinity focus, each focusing adapter must be precisely designed to match its corresponding lens' focal length. A...

Create a custom lens adapter for your point-and-shoot camera lens by using this design, specifically made for SONY FE mount. Download the file and modify the piece marked with "BIG MINI F" to suit your optics. ...Note that the center part is just a...

The lens is held together using stitches, since I didn't want to require screws for this project and I wasn't confident my printer could print any other fastening system well enough. There's also some black electrical tape on the insides to block...

... For added precision, photographers can fine-tune their focus on the Lens Focus tab.\r\n\r\nThe device is custom-built for LM-E or LM-FX commercial products, specifically designed to enhance the functionality of the "LM-E or LM-FX Helicoid adapter".

This is probably not a good first project for those adapting glass from fixed lens cameras and you should practice on more common and cheaper models to practice on ways of removing lenses. The Mamiya is straightforward to work on. Once the lens is...

twist helicoid with 3 pitches

The device converts translational motion to rotary motion using a helicoid mechanism similar to a camera lens or mop spinner. Before moving into production, some improvements are necessary: clarifying part dimensions, designing a frame for mounting...

... z(t) = 2t/3. ...The parameter u ranges from 0.25 to 1.25, while the parameter t spans from 0 to 2Pi. Both .stl and .form files used for printing are provided. Additional information is available at http://mathvis.academic.wlu.edu/2015/07/27/helicoids/.

>"An isotropic helicoid may be made by attaching projecting vanes to the surface of a globe in proper positions; for instance, cutting at 45° each, at the middles of the twelve quadrants of any three great circles dividing the globe into eight...

Customizable lens hoods designed specifically for smaller lenses offer unparalleled protection and versatility. ...Tailor them to your unique needs by adjusting various parameters for a seamless shooting experience.

This is a model of part of a helicoid with parametric equations x(t)=u.cos(t), y(t)=u.sin(t), and z(t) = 2t/3, where the parameter u varies between -1 and 1. The parameter t ranges from 0 to Pi for the half-twist. ...Additional information is available...

... disperse. Was thinking what if I combined the Armadillo Hexagon Structure that gives it a bit of Puncture resistance with the Helicoid of the Mantis Shrimp that gives it Impact resistances into the Interlocking Tiles just for fun Hope you enjoy!

Carbon fiber helicoid tubes, woven in composite form, are the subject at hand.

... shape of a corkscrew. This design allows for smoother movement and less friction between the nut and the telescope's mounting system. ...Some people even argue that this type of nut is more durable than other types, but I'm not entirely convinced.

... instrument known as a telescope helicoid bolt. ... To adjust your view, keep the eyepiece stationary while carefully turning the helicoid bolt in either direction – this simple action allows you to precisely control the focal length of your device.
