Have been looking for a good paper towel holder for in the kitchen. I couldn't really decide on whether to go for a standing one or one to wall mount. In the meantime, we typically put the paper towel on the kitchen robot which then inspired me of making a paper towel holder on the kitchen robot. I looked at how the bowl hooks into the kitchen robot and created the same connectors on the holder. So the holder can be hooked into it making sure it's properly fixed. The small 3 pins help with locking in / out and holding the paper in place.
