I’ve seen a lot of planes get damaged when kids carry them home from my workshops. Dogs, siblings, parents, wind and other hazards cause a lot of damage.
I’ve tried having the kids bring boxes and about half show up with a box that is smaller than the plane. Using big boxes to put lots of planes in is haphazard.
I tried carrying them back and forth for the kids (between sessions) but that’s a lot of work.
I have been experimenting with various ideas and this is the current version.
It’s a little box that can hold one or two Squirrels with the wings removed.
