Nano Biscotte v3 Chassis

Recently we build a custom saber and needed a very tight fitting chassis for a Nano Biscotte v3, that supported a 20mm speaker, Li-Ion 18650 battery and a 2.1mm Power Jack in a very tight space.

So we designed this chassis. The speaker and NBv3 pressure fit into the chassis, you may want to add a drop of hot glue to the back fo the speaker if it is going to take some abuse. we suggest adding a bit of electrical tape over the NBv3 also just to help ensure it does not pop out as you are working
