This chassis have been designed with solidity in mind for all those sabers that need to withstand heavy impact when used for lightsaber combat.

The design is very sturdy and will accept the following components:
The chassis will lock in place between extension and pommel.
Board and batteries can be secured to the chassis with some thin PVC heatshrink. The speaker must be glued and secured with PVC heatshrink.
Warning: it may not work with very short pommels, like pommel style 11 or alike.
