Caliber Stamp Guide, Firearm Barrel

Have you struggled with stamping the caliber designation on gun barrels, using tape and prayers to try and avoid the results looking like a ransom note?  This 3D printed guide clamps around the shank of the barrel and guides your steel stamps (1/4″ square body size) in a straight line and sets the letter spacing perfectly for 3/32″ high characters.  Clamps to barrel shanks from 1.125″ to 1.350″ in diameter and allows for strings of up to 17 characters per line.  Simple to print and use, it will change your life!  With this download, you will receive 3 separate files for importing into your slicer and 3D printing, plus a PDF image of the product drawing detailing it’s assembly and use.

I put a fair bit of time into this design, printed prototypes, and stamped several barrels before I was happy with it.  Please do not share these files around or sell the printed parts and/or files, lest the copyright karma gods visit you in your sleep…
