Have you printed the popular Bone Bag model as posted by @鸦鸦101 and featured by @Uncle Jessy?

But your wife asked you how she was going to print put things inside without them falling out?

This is a great addition to keeping her personal items safe in this amazing Halloween accessory.

Printed in Bambu Red TPU95 this fits perfectly inside the full size model. 

Prior to assembly of the upper sections and handle simply fold and slide this TPU insert inside.

Finalize assembly and Bam you wife will not lose her precious items.
