Full Description

This is an first release version of a dual-arm parallel marking gauge / center marking tool for woodworking and general layout work.

The tool is designed to help mark consistent parallel lines along a workpiece, for example when laying out borders, center lines, grooves, joinery references, or repeated edge offsets.

The two outer arms guide the tool along the edges of the workpiece, while the center ruler / marking slot allows you to draw or scribe a line in a controlled and repeatable way.

If you print and test it, please let me know what worked well and what could be improved.

Features

• Dual-arm parallel guide design
• Useful for marking parallel lines and layout references
• Adjustable / modular concept
• Printable parts for workshop use
• Designed for woodworking, framing, layout, and marking tasks

Print Notes

• Print with enough walls/perimeters for stiffness
• PETG, PLA+, ABS, ASA or similar materials should work
• For workshop durability, PETG or ASA is recommended
• Check the screw and knob fit before final assembly
• Depending on your printer tolerances, minor sanding or drilling may be required
• No guarantee yet that all tolerances are perfect — this is still an alpha release
