Incorrect rendering

[ScottNudds]

Should produce a frame, flat background for the frame and a 3 filament bride that is rounded on top and flat on the bottom.

The background should be smaller than the frame and sit inside. The braid should be smaller than the frame and sit inside.

@ScottNudds, what are you seeing or what is incorrect? Are you referring to the different colors?
Also: Which browser are you using?

With your script I see the following:

Seems to be working now.  What I was seeing before was a small cube in place of the plate, which did correctly subtract from the frame but as a small cube rather than the larger properly sized plate. The braid had an incorrect profile with a rounded bottom on the individual theeads and a square top. Rendering is correct now.

I did a lot of fixing after posting it to Reddit - I guess that got fixed somewhere along the line. I'm closing this issue.
Thank you for your feedback!
