This model prints nicely with very little clean up, all the parts go together perfectly. I would recommend printing at a lower speed for better quality. I added the base and number tag for humors sake. If you have a twisted sense of humor like mine, you can take one of those personal message cards, remove the recording device, record 5 seconds of silence then a large explosion sound wave, install in grenade with the activator being triggered by pin removal. The empty cavity (for spices) magnifies the sound even better than I thought.
