Macro Add-On for Mini & Classic


A macro lens upgrade for the OpenScan Mini & Classic: sharper detail, higher magnification, at a price you choose.

This choose-your-price model is a limited-time experiment. See "Why choose your price?" below for the full story.

Features

  • Scan volume of roughly 4x4x4cm with OS Mini, 6x6x6cm with Classic
  • Greatly increased accuracy and resolution of the scan results
  • ~2.5x magnification

Compatibility

  • Full: OpenScan Mini V1, V2 / Classic
  • Partial: Blackshield (Midi/V2) — needs slight modification of the ringlight cable

In the box

  • Ready-to-go macro unit for OpenScan Mini, Classic, and custom builds (using the stock Arducam IMX519)
  • 2.5x Macro Lens
  • Ring light + cross-polarizer
  • Lens cover

Some raw scans

Assembly

  • Replaces your original ring light and reuses the existing camera mount
  • Mount with 4× M3x12 screws, attach the camera module with 2× M3x8 screws (included)
  • Connect ring light and camera — ready to scan

Note: No camera included. Arducam Hawkeye is only compatible with Classic (minimum focus distance issue on Mini).

Why choose your price?

Pricing open-source hardware honestly is hard. Once you account for development time, production, and the real costs of running a small business, €108 is roughly what it takes for the Macro Add-on to be somewhat sustainable.

You decide what's fair to you! What that means will look different for a hobbyist just starting out than for a business that profits from this and future developments.
