Hi,

I tested a method.

First you use your wall and apply the FatLines plugin.
Use it with your wall in the good view (good view depends to the perpendicular you use... test each or rotate your wall to be horizontal
With your file I use 0.015 inch large
delete or hide your original curves

With new curves, extrude them

You have now a solid to flow on your wall.

Flow it using a plan adapted (cf my picture where plan is in green)

To finish your wall, do a boolean difference between wall and 3D bricks border


Adapt this method with right adjustements in size of borders, in depth, in source plan of flow...


Beware about faisability... I don't know if printer could do so tiny details...


All done in MOI3D with a single plugin (Fatlines Thanks to Max)
