Adjustable Router Frame – Modular, Precise, Versatile

This adjustable router frame is a modular system made of four identical 3D-printed ruler segments, designed for precise routing of rectangular or square cutouts.

Thanks to the integrated measurement scales, dimensions can be set quickly and accurately. The modules are connected with a clever twist-lock system, creating a stable, infinitely adjustable frame.

Features:

• Modular design: 4 identical segments, easy to expand
• Quick setup: Frame ready in seconds
• Infinitely adjustable: Flexible size adjustment for different projects
• Precision scales: Accurate work without extra measuring
• 3D-printed construction: Lightweight, robust, customizable
• Versatile use: Suitable for wood, MDF, plastics

Assembly of a module:

• Each module consists of a ruler element with an integrated scale and a connector element with twist-lock.
• The connector element is slid into the end of the ruler.
• The twist-knob is turned to secure the connection.

Connecting four segments into a frame:

• Prepared modules are connected at the corners.
• The twist-locks are tightened to keep the frame stable.
• The frame size can be adjusted continuously without losing stability.

Advantages:

• Fast assembly and disassembly without additional tools
• Modular expansion – can also be used as a partial frame or single segment
• Exact scaling thanks to integrated measurement scales
• Compact storage – all segments can be stacked flat

Custom templates – more flexibility:
The router frame can be equipped with custom-made templates. This allows you to insert perfectly fitting jigs, for example for drilling templates, special cutouts, or dovetail joints.
Benefits of this extension:

• Individual adaptation to specific projects
• Repeatable accuracy thanks to fixed templates
• Combines standard frame and special tooling in one system
