flat pack grill bbq

Flatpack BBQ Grill - Design Review Needed This is a flatpack design intended for CNC cutting from [3]mm steel. The goal is a "no-weld" . I am currently running into a problem with the interlocking tabs / assembly mates . Technical Details: Software: SolidWorks 2024 Material Thickness: 3mm Manufacturing: CNC Plasma cannot get the side panels to mate correctly Any advice on how to clean up the Feature Tree or fix the geometry would be greatly appreciated!
