I'll just cast my pearls elsewhere next time.

Nicely done keep posting! sheet metal drawings are great. If you want them to shear off you can consider riveting them on the outside of the tray so they are on the outside surface and not trapped; or deflectable tips. You might even consider coarser track versions....lots of heat to get rid of. I start to loose third it's so bad
