SAK Pen Scale

This Scale is a modification to a 58 mm Swiss Army Knife to oppose the OEM pen scale. I wanted to make a scale that had simiar functionality to the OEM scale while improving on certain limitations. The main improvments are a 3 position locking mechanisim and offering more variety when it comes to pen replacments with slight modifications. I also made this to make the ultimate SAK based on the Jettsetter for Air Travel. I currently have 9 tools in this edc set up listed as follows : 40 mm RulerTweezersTooth PickEye glasses Philips and flat head screwdriverPenScissors (Rounded Tip)PH1 screwdriverBottle OppenerThe ruler scale with the dual slots is linked here : https://makerworld.com/en/models/2112526-swiss-army-knife-dual-scale-replacement-58mm#profileId-2285644 The following is the instructions for making a pen replacment for this Pen scale :Gather Materials [Metal Wire Shears, Ruler, 2.2 mm Pen replacment, Bambulab Lubricant Grease, Paper Towels, Sink, Optional (B7000 Glue)]Measure th
