Funko Bitty Pop Display Case Guard

Disclaimer: 
This design worked fine for me. I am not liable if anybody manages do damage their figurines or display cases with this.  

My Funko Bitty Pops kept falling out of the display cases. I designed this part to hold make sure they don't fall out when the display case is tilted. 

I discovered that there's at least two versions of the display cases. This design does only work with the version that has the small cutout on the back and the small bit on the bottom of the case. 

For visibility in the pictures, i printed some in green but i recommend using transparent or white filament. 

Printed in eSun Transparent PETG filament.
