This year I finally got around to making my own nichos (shadow boxes, or mini shrines). I shared my process, which includes resources like adjustable templates and example code, via the Chibitronics website. You can view the full tutorial here , and read the blog post introducing the tutorial here.
A big thank you to the Chibitronics team for inviting me to share my work, and for supporting me in creating this tutorial!
