Angle Finder/Protractor [Updated Jan 2025]

This is a remix of https://www.thingiverse.com/thing:1592398.

I wanted an angle finder that did not extend below the protractor so I remixed the above. Added a window on the measuring arm to improve visibility of the angle numbers.

I used a rubber o-ring to secure the arm. It works great. Assorted o-rings can be purchased from Amazon. Example is https://a.co/d/17CngNZ.

[Update Jan 2025]

• Metric centimeter marker lines were added to the bottom flat/straight part of the protractor for additional function.
• A thin visual line guide is now present to aid angle readability. The thin line can be colored using a Sharpie for those without AMS/MMU.

If you have an AMS/MMU, coloring the visual guide strip provides good color contrast from my own print out especially when coupled with colored numerals on the protractor. I hope you find this useful.

I chopped off the arm extension below the protractor and rounded it off. Also added a viewing window for better angle viewing.

Update Jan 2025

• Added centimeter ruler function
• Added angle visual aid to finder arm window
• Updated protractor is sized at 12cm diameter
