Caliper with secret compartment

Just some thing i printed for my wife colleague who just turned 60.

There is one custom in Germany, where i currently live, to give someone money for birthday but to hide it somewhere previously. Since this person work with calipers i made him one with secret compartment where we put the donated money.

I print it using this method: http://schlosshan.eu/blog/2019/03/02/prusa-i3-mk3-real-multicolour-prints-without-mmu/?fbclid=IwAR0WPPBhrGVtPKjeeQGYWoN66Ax7LvfTseY4hmUEc88DazlUDDeZ_ckYXsI
