[REMIX] Self Centering Gauge (Inch Markings)

Overview

I saw the original centering gauge by Chris (Aero)Engineering Design and I loved it! I was particularly impressed with being able to draw a line of a certain length from the edge of a block. However, living in the US makes the original millimeter marks largely irrelevant. Until we fully switch over to SI units, I figured I'd remix the original part to include those markings in inches instead of millimeters. You can use a mechanical or carpenter's pencil for the center mark and a mechanical pencil for the outer markings.

Changes

I took the original chamfered design and made three major changes:

• The main body does not include the woodworking angles of the original design.
• I made holes for the stoppers to fit into the main body.
• The marks are in increments of 1/8" up to 1". The distance from the edge of the stopper to the edge of the main body is 1/8" like in the figures below. 

Printing and Construction

You need to print the main body and two stoppers. For the main body, I followed the original design's suggestions of using four perimeters and 30% cubic infill. You don't need to use supports for this model. I used three perimeters for the stoppers. You will also need two 1/4"-20 bolts and two corresponding nuts. I used a 1.5" bolt, but if you have a shorter screw, you can reduce the height of the stoppers in the slicer. Happy printing!
