Fred,
Thank you. I tried playing around with your WB. Can you or someone show which WB or tool to make holes in the ribs and give them thickness so I can 3D print them. I tried to use the part design work bench and sketch but Freecad didn’t like that because there was no body container. I think I am mixing work benches so a step by step instruction would be nice.
I confirm there is a problem

, until I find a solution here are two workarounds :
two ways to resolve your problem :
-after the rib creation, go to draft WB
-first way : transform the rib in a sketch : a clic on

, after this operation you can extrude the rib, use the part WB etc..
-second way : downgrade the ribs: a clic on
