Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4650422.
This is a refinement of my original design, https://www.thingiverse.com/thing:3693712 . After using the original design for over a year I have found and corrected the issues I didn't like. This is a redesign of the original and is not compatible with the original design. So unfortunately the parts are not interchangeable.
To make a 1-30 corner use the 1-60 left and 1-60 right. To make a 1-60 corner use the 1-60 left, two 1-60 center sections, and 1-60 right.
Everything else should be pretty self explanatory.
If there is another location you would like to see the guardrail for please let me know.
