How to extrude complex grid without creating new parts

Hi,
I am a beginner on Onshape and run into problem ( in Extrude 1 step) where I can extrude with New (which generates a lot unwanted parts) but not with Extrude - Add - Merge All (which gives merge scope error but does not allow select Merge scope). Current model prints correctly but has 69 parts. Question is - how to model it as one part with same printing result as now (how is right way to get same result)?

Hello. That was weird. The only way I could get it to work was by selecting sketch faces one by one until the number of pieces multiplied. If it did, I removed the last selection and selected another face adjacent to one already extruded. I'll bet someone else knows why I had to do it that way. But of course, there probably is another way. - Scotty
The sketch of scroll work has a number of items that don't work well for the extrude. There some line work that is repeated but offset from original location, lines and curves that are not coincident leaving small gaps. There is also some curves tangent to lines that generate non manifold geometry.
I recommend the learning center to help get you started.
