Shapes are filled with: Rice beans, bells, wood pieces and the sound device from a music card
How to assemble:
The Bottom plate have to be put in place when assembeling the inner case.
Best practise is to start gluing the inner case with the bottom piece in place and then start adding the outer siders one by one.
High picth sound wont make it through the encapsulated shapes. So no point in putting X-mas bells in them then. Also the sound from the music cardwas wery faint. Recomend cutting small holes in the shapes to impruve sound quality.
