Help Finding Road Guardrail Post

[haasmarc]

I remember seeing someone post some info about road guardrails that they 3D printed.  I have done several forum searches but I can't seem to find the post.  I am working on a road bridge and I am trying to print some guardrails but am not liking the results so far.

Does anyone remember the post or the person who printed them?

Hello   I designed a steel barrier with a bit of detail.  It is in TinkerCad.  The .stl file is:
https://www.tinkercad.com/things/6YlAuiioARM-steel-roadside-barrier-n-scale
It is open for use, just no commercial printing.  I printed these parts 7 or 8 at time, 30um steps to get the detail.  It is flexible, but do not overcook it in the curing system.  I painted with Aluminum Tru-Color and acrylic brown.
Have fun.

Thanks for those links.  I printed some guard rails and when they came off the printer, they were all wavy. I mean really wavy. I cleaned them and expected to just toss them but after cleaning they started to straighten out.  Hopefully I will be able to use them.  I think the original post i was looking for might have been in a weekend update. I just don't  remember. I think they were printed in white.
