Description
Modular M42 Macro Extension Tubes – 3D‑Printable Kit for Precision Macro Photography 🔍📷
Overview
This modular set of 3D‑printed macro extension tubes is made for lenses with the classic M42 screw mount (42 mm × 1 mm pitch). By increasing the lens‑to‑sensor distance, the tubes boost magnification for detailed macro work—especially with vintage optics 🪻🔬. Combine them with any DSLR or mirrorless body via a standard M42 adapter and stack to taste.
📏 Tube Lengths Included
| Length | Typical Use | Note |
|---|---|---|
| 10 mm | Fine‑tuning focus in long stacks | Place this one furthest from the camera for extra stability |
| 30 mm | Moderate close‑ups | Pair with 10 mm for 40 mm total |
| 50 mm | High magnification | Stackable with any other |
| 100 mm | Extreme macro shots | Start here when you need the most reach |

ℹ️ Why M42?
The M42 screw mount—popularized by brands like Zeiss, Asahi, and Soviet manufacturers—remains a favorite among macro enthusiasts for its purely mechanical design, affordability, and easy adaptation to modern digital cameras.
