230425: v0.1 inital version Work in progress for a proof of concept that a focus helicoid can be made by 3D printing. Currently printed in 0.1 layer height in eSun ABS+ on a Voron Trident. This version should result in ~6mm movement and…
This is a remix of the Quadrifilar Helix Antenna by @ jhsandell for 1090MHz (ADS-B) The following updates have been made: The 'bug' that jhsandell noted where the code was using diameters rather than radii has been fixed This version…
Needs to be printed with 0.1mm layerheight or better. 1 June 2025: added “M65Front_Copal_GENERIC v1” both as STEP and f3d files + “M65_flange” as STEP. for easy modifications.
Important updates 2026-02-27 : Got a new set of helicoid adapters and found that they have around 313 degrees of rotation compared to 167 degrees on my previous ones. So I added"extension" and "max rotation" as adjustable parameters to be…
Didatic model to show a pair of helicoidal gears coupling reverse axles. Uses 05 wood screws (flat head 3x12 mm). Best print with PETG.
This is a remix of the Focus Helicoid by amoser from the Printables website. https://www.printables.com/model/462315-open-camera-focus-helicoid An interesting project that is defined as a “work in progress.” It was not yet functional…

Differences of the remix compared to the original Fixed a bug that prevented the original design to operate properly increased the travel distance from ~3.8mm to ~10mm Added male M42 threading in the back to make it easier to combine with…
This helicoid adapter provides 10 mm of precision focus travel, compatible with the popular M42×1 front/back interface used by many vintage lenses and camera adapters. Intended for adapting projector lenses, odd optics, and other fun DIY…
All in all, I loved this light and portable set up. Great inspiration + starting point from @Spotmatic. It is a night and day difference compare to my Hasselblad 500cm + 60mm distagon. With a bit of practice, the 65mm Mamiya sekor is an…
A friend recently asked if I could print for him an Open 6x12 Camera. None of the available lens cones had the correct flange distance, and I wanted to give him the ability to have some degree of focusing. I decided to combine the work…
Engranaje helicoidal doble “A” y “B” para rodamiento 6000 2rs
Prints no supports. I recommend using black pla. Check it for light leaks, use a flash light in a dark room to inspect it. This light leak can be desirable if you're going for a certain look. Up to you! I printed at .2 with a .4 nozzle…
This is a ring to mount a Copal 0 (or similarly sized lens/shutter combo) to one of the M65x1 focusing helicoids. Did not think 3d printing such fine metric thread would work, but it does. Printed with 0.2mm layers, and a 0.6mm nozzle…
This model is featured in figure 6.21 of Visualizing Mathematics with 3D Printing . Category: Math
As it is a basic design for verification, there is a risk of the lens falling off while focusing. Please use it carefully.
Tapa curva helicoidal ventilador 40x40
Very easy to print: Better to print it in PETG and as shown on the first picture to increase robustness. The original one (broken!) is on the second picture.
I had this old Ricoh Auto Shot from my parents that they bought as a decoration, lens was good so I disassemble it, took measures and made a thread like a Helicoid to focus it, works perfectly I STRONGLY recommend printing the lens holder…
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…
An adaptor to attache ILEX #3 Shutters or Barrels to M77 Helicoids that is used in various 3D printed camera builds. Thread specs.: Ilex 3: 1.913"x40 TPI M77 Helicoid: M77x0.75 Printing suggestions. 0.15mm layer height Avoid crossing…
I made this mostly as an aid to measure actual focus distance for camera building, but I'm sure some adventurous soul would find some photographic application for this. I'm sharing in the hope that it might be useful. Thread Specs.:…
