My social mediaβs all about the poop these days. But here's another kindβ¦
In this case my wife suggested a holder for our dog poop cleanup bags which made a quick fun project. My MK4 handles flex, TPU-like, filament like a champ so I decided to use flex for the cap material to get a snug fit with a nice feel and texture. We keep this at the exit through the back door.
