You’re welcome @tdwilli1! Would this have helped you, or help others in the future?
I just uploaded Strut Plates .SVG files sized from 480mm - 1700mm, in 10mm increments, to github.
Edit number in the URL to the nearest 10mm size you need.
So, now folks only need to generate a Custom sized Strut if they need millimeter precision (that’s not a multiple of 10), in which case this video may help folks not familiar with OpenSCAD:
Edit: LR3 Calculator might be extended to let Users quickly download Strut .SVG correctly sized for their build. For more details, see this post.
