Many years ago ~ I use to work inside ships aligning & welding items, and if you have ever been inside a ship you know nothing is straight, level, or easy (Other than creating a leak) …




Therefore, one needs to be able to mount ‘measurement items‘ in specific places and measure out from those areas to triangulate distances, etc.



Several years ago I machined some measurement guides out of Aluminum for Centering threaded holes and made magnetic mounts for some of the hole measurement inserts.



Decided to design a version to 3D-Print up several new ones for a current project …



3D-Printing allowed me to design without having to worry about 'plastic injection molding' draft angles.



The Key to the design is one edge is perfectly aligned with the Center of the hole so that when the tape is pulled against that edge it aligns with the center of the hole for measuring Center-to-Center hole measurements.

My AFINIA H-480 3D-Printer creates very accurate parts allowing the center hole measurement to line up very well with the 3D-printed insert edge ….

3D-Printing Resolution for the AFINIA H-480 is 0.20mm ( 0.0079″ )



The Measurement Inserts are also designed so they are exactly 1/2″ from any flat edge to the center of the hole being measured with the Tape …



Many times I will run a guide string to get a visual of where items are going to run through other structures for which I am designing my items to fit within …



Created a quick ( unedited ) Video talking about how I use these items …

Nothing Fancy but they work for what I need.

CHEERS!!
