KnockBox SplashBack

My knockbox is a fairly common model found on internet shops. It's basically a simple box so when you knock the puck out you risk splashing the back wall with coffee stains.To prevent this, I made this splashback, quick and easy to print and does the job. INSTALLING: Place double sided tape along all the edges in contact with the box. The inside rim is deliberately about 1mm larger than the knockbox's rubber grommet. This allows the grommet to be “pinched” into place. The internal metal container rests on this grommet not the splashback. Seats correctly and still able to remove/replace the metal internal part for emtying.
