About this 3D model

I was thinking about my kids going back to school post quarantine and needing a safe place to stash their mask during lunch. So I created something quick, easy to use, no pieces to lose, can be attached to a bag...and just the right size to hold a cloth mask. It is not a perfect solution, I know, but hopefully will be better than laying a mask on a table or desk, or dropping it on the floor.
