Minimalist knock box

Knock box I designed inspired by famous brand in the industry as I wanted something different than what's available. Notes for printing: The profile contains some modifiers to strengthen the most important parts.The ironing was calibrated for BBL PLA basic, cannot guarantee it will work for different brands/materials. Need to adjust it or turn it off (object settings)The “knock plate” should best be printed in TPU but PETG also works. PLA might be too brittle. The box itself can be printed from PLA no problem.
