Customizable letter/number punch guide

Serialize your metalworking / smithing / bubba parts like a pro! This simple but handy tool makes sure the digits in your inscription are aligned and evenly spaced. Fully customizable so you can adjust the tool to fit your punches and choose letter spacing and length to your taste.

***How to use***
1. Measure your punch set and adjust the measurements in the code.
2. Choose letter spacing, number of characters and other "arbitrary" parameters to fit your projects.
3. Print the part - takes up very little material and is fast!
4. For better results, affix the guide to your part with something like painter's tape. At the very minimum, draw alignment marks with a scriber so you can keep the guide aligned. Better to use both methods :)
5. Punch away.

NOTE: If you choose the thickness value around 1.5-3 mm (depending on material used), your guide may be flexible enough to accommodate inscribing on curved surfaces such as across a barrel.
