Chassis to fit a Saberforge lightsaber hilt. This is made to hold a 18650 battery and 28mm speaker which are not included. Has a flat top surface to which to attach a range of boards. We print these to order, often tuning the length to suit your electronics cavity (leaving enough for wires but no 'rattly' gaps). Variety of colours available. Note your preference(s) in the order notes at checkout. No RCP hole, but there is a clever way to fit one on a longer chassis :) It will work with the Premium or Bass speaker
