Could you possibly make a weapon (using the same model as the printer but grey) which shoots a beam similar to the printer, but have the beam do damage to bots? Call it the 'Ghost Blaster'. I feel this request is simple enough.
If possible, I could also use an item that uses the same model as a 1x1 brick, except lime green. Call it 'Ecto-Cooler'. When used, it makes a slurping sound, and that's it. If you are unable to make this, that is okay, the first part is the only one I really need.
