lens helicoid 3d models

... 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 with slightly bigger flange distances. ...

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...

L39 Focusing helicoid for NIkon RF lens. Fits both internal and external bayonets. ... But plastic L39 mount is too weak to use for telephoto lens.

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...

This version uses the lens from an old Kodak Max HQ disposable camera, which has a two-element lens. 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...

A lens mount with integral helicoid focusing for vintage M39 enlarger lenses. These focusing adapters have to be different lengths, depending on the lens' focal length, in order to achieve infinity focus. Several barrel lengths (13,22,33mm) are...

Leica M Focusing helicoid for NIkon RF lens. Fits both internal and external bayonets. ... Not tested with Leica M cameras.

L39 Focusing helicoid for NIkon RF 50mm lens. Rub the helicoids together when assembling it. It will separate at the position shown in pic2. ... Parts list helicoid_outer.stl 1pc helicoid_inner.stl 1pc helicoid_stopper.stl 2pc lever.stl 1pc...

The mechanism of transformation of translational motion into rotary - helicoid (like foto lens or mop spinner). Some necessary improvements for pre-prodaction: 1. Clarification of the basic dimensions of parts. 2. Development of the frame for...

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 goes between 0.25 and 1.25. The parameter t goes between 0 and 2Pi. There is both the .stl file and the .form file I...

By making the globe and the vanes of light paper, a body is obtained rigid enough and light enough to illustrate by its motions through air the motions of an isotropic helicoid through an incompressible liquid. But curious phenomena, not deducible...
