Roll Top Pencil Case with Mini Sharpener case

I was looking for something to design and make for a friend of the family's young son.The idea I came up with was a Roll Top Pencil case along with a mini Roll Top Case for the Pencil Sharpeners or Erasers.The design itself was quite tricky and getting the components to fit correctly was a challenge, hopefully, I think I got all the issues sorted out.I designed the pencil case first and when that was complete, I thought why not model a mini version for the sharpener or Eraser, paper clips or something else.Assembly details are as in the attached video, or you may come up with a better way, as with all new projects nothing is written in stone so to speak.Assembly of both cases is really easy and requires CA Glue or an alternative, the key is to use the CA Glue sparingly.Be the envy of the class with these great Roll Top Cases.Thanks for Looking.
