LensDock 3 – Modular 7-Mount Lens Stand

LensDock 3 is a modular three-lens stand designed around one simple idea: one universal base, interchangeable inserts for different lens mounts.

Instead of making a separate stand for every camera system, the stand uses three identical octagonal sockets. Each socket accepts a removable lens-mount insert, so the same stand can be configured for one system or mixed between different systems.

The current version includes inserts for Sony E / FE, Canon RF, Nikon Z, Canon EF, Nikon F, Fujifilm X and L-Mount. These seven mounts cover many of the most widely used interchangeable-lens systems, including lenses from Sony, Canon, Nikon, Fujifilm, Panasonic Lumix, Leica, Sigma and other compatible manufacturers.

You can install any combination of three inserts. For example, the stand can hold three Sony E lenses, or a mixed setup such as Sony E + Nikon Z + L-Mount.

The inserts are held inside the stand by their matching eight-sided geometry. This prevents them from rotating when a lens is attached or removed. The fit is intentionally secure, and access holes in the bottom of each socket allow a tightly fitted insert to be pushed out when you want to change the configuration.

The stand is built as a substantial, rigid structure rather than a lightweight display holder. It is suitable not only for keeping lenses organized on a desk, shelf or working area, but also for carrying the stand with mounted lenses using the integrated central handle. Actual strength will naturally depend on filament, printer calibration, layer adhesion and print settings.

My prototypes are multicolored because they were printed from joined leftover filament ends. The color changes are therefore simply a result of using available material and are not required by the design. The model can be printed in a single color or any combination you prefer.

There is no required filament type. PLA, PETG, ASA, ABS and other suitable FDM materials can be used. Choose the material according to your preferred balance of stiffness, temperature resistance and impact resistance.

The downloadable files are organized into four categories: Prusa, Bambu, Anycubic and STL. Each category includes single-color versions of both the main stand and the individual lens-mount inserts, so multicolor printing is not required.

Important: print the required lens insert first and test it with your lens before printing the complete stand. Lens mounts require relatively precise tolerances, and differences in printer calibration, extrusion, material shrinkage and first-layer settings can affect fit. Confirming the insert first avoids wasting time and filament on the larger stand.

The modular system also means that changing camera systems does not require replacing the stand. Print a different insert, remove the previous one through the access opening underneath, and reuse the same base.

Included mount inserts:

• Sony E / FE

• Canon RF

• Nikon Z

• Canon EF

• Nikon F

• Fujifilm X

• L-Mount

The design is intended as a practical storage and handling system rather than a decorative lens display: three secure positions, one universal stand, and replaceable mount-specific interfaces.
