Now that the team's making progress with the electronics for the handle design, Ben's working with Autodesk Fusion 360 to create the 3D model for the 3D printer to house the trigger and the protoboard. The rest of the super glue gun case also needs to be modelled and Fusion 360 helps by being able to import some parts to be able to get the sizing right, for example with the bearings for the hot end feed system/nozzle. It's not only the physical design that needs some tweaks, the team are having difficulty with math calculations on the ATTiny hardware, and Felix is repairing the electronics for the hotend and motor control. How's your C programming? What would you design differently? Join the team on the element14 Community!
