3D model description

Since my last 3 designs were so popular and demand for other lenses was high, I designed a new rehousing for the most sought after lens: the Helios 44M-4

Next up will be the mighty Mir-20M f3.5

DISCLAIMER: this is Version 1 of this design. Changes might be added in the near future (I welcome your feedback too!). The first prototype works good so far.

It works great and enhances the already impressive capabilities this little lens has for you.

You get cine-style gears for smooth focusing while still maintaining the focus scale visible.

The parts fit very snugly on the lens so there's no need for taking the lens apart. All parts are held together with grub screws.

The front diameter measures 95mm, so works with clamp-on mattboxes while it maintains an inner diameter of 82mm for screw on filter (step up rings needed).

I also encourage to adapt the M42 mount to an EF mount.

Parts needed:

  • 12x M4 grub screws

  • 4x M3 grub screws

  • Step up rings: 49 -52, 52-55,55-58, 58-62, 62-67, 67-72, 72-77, 77-82

  • tape & sanding paper

Info:

Some parts might need some sanding to fit perfectly. Also using ducktape helps to get the right fit. The crews secure the parts additionally.

If you have any input on the design let me know! I'm constantly updating the designs of my rehousings!

3D printing settings

Layer height: 0.2mm (go lower for even nicer finish)

Filling: 10% (more is not really needed)
