Marking Gauge for 26mm/1mm Ruler

This marking gauge is optimized for a 26mm wide and 1mm thick rule.
There is a 0.3mm clearance; I will attempt a tighter version in a potential update.
The screw is very large for effective locking; the screw pitch is the standard metric M20 with 0.6mm clearance—ideal for a secure tightening.

I opted for PETG to mitigate moisture-related issues and ensure usability in all conditions.
The profile is 4 walls with 30% triangular infill. Experiment with different infill percentages based on your preferences; I find this configuration exceptionally robust.

I welcome any feedback should modifications be necessary.

Happy printing
