The decision was made to shrinkwrap a traditional printable grid pattern on a smooth speaker stand shell.  The thinnest horizontal walls in PLA are .4mm.  A .4mm vertical wall requires a .2mm nozzle & a lot of time, so it would be a .5mm thick shell.

Blender happens to shrinkwrap surfaces on surfaces.  The trick is selecting Project, X & Y axis.  Then, it properly creates a solid with the solidify modifier.  

The target needs to have parallel walls.  The process leaves a lot of junk.  It's not parametric.  After creating a generic corner section, the corner sections would have to be fused & transformed in Blender to make the stand.  There would be a solid column where the corners joined & the fusion would just use booleans.

There could be a simple python program which mapped a sketch on a hard coded corner section.
