Modular Candy Bar Dispenser

This is a candy bar modular dispenser vending machine. It's a V2 to my original 3D printed vending machine which used a coil. This version uses a chain with prongs to push candy along a tray. There are now 2 sizes available:100mm for small chocolate bars150mm for large chocolate bars. Both sizes assemble the same way. It has a handle for manually dispensing, or a module for attaching a Nema 17 stepper motor for motorizing your own 3D printed vending machine. This model is designed to require minimal supports, and no additional parts other than nuts and bolts. Build InstructionsDispenser FrameAll modules attach together with M3 x 6mm self tapping screws.The frame is designed to be modular so you can swap out modules, or print it longer / shorter. The whole frame will take a few minutes to assemble. Back Module - This either uses a short hex shaft with a hex end stop and acts as a back pulley, or you can print the motor one and install it with a Nema 17 to motorise this candy dispens
