Summary

Original idea for a gift on any occasion.
It's a remix that includes:
1) Side flaps widened so as to be permanently closed with bioadhesive tape or glue.
2) It has spaces between the body of the letter and the joints that bend, so you can print them in TPU, changing thread with normal or bamboo printers.
While v2 has the structure and joints joined, therefore entire layers to be printed in TPU.
3) Requires 30x30 plate unless you make it smaller
