Creating a void so that protolabs can IM my part. Base piece passes, but the tabs are too thick. I created a void to fix that. Too ensure a through hole, I made the “void” .02" taller and offset it by .01". For some reason it still leaves a void sized surface after the Boolean difference. I tried building the void from an extruded surface and from a capped closed curve. Both leave a surface behind which can’t be deleted. Not sure how to post my model.
Thanks
