US Monies Encasement Thingy Gift

Embedded US monies in a small 3D printed gag gift. The monies will be completely enclosed by plastic. The plastic is NEVER extruded directly onto the monies.
I decided to do this as a learning gag Christmas gift for my niece and nephew. I will tell them the material and the process used. Next, I will encourage them with some hints on how to best remove the monies.
This fits two US bills.
