Seeing Brandy in the video and see how difficult it can be for her and others taking a sponge to wash dishes daily, I thought in a simple but effective design, which had teeth to grab the sponge and a support with something flexibility for curved parts, such as a glass.
1. Place the sponge between the teeth of the printed piece. See photo Step 1.
2. Take a paperclip and unfold it or use a piece of wire 1mm thick. See photo Step 2.
3. Slide the wire or clip through the hole in the printed piece to the other side. This will prevent the sponge out easily. See photo Step 3.
Printing at least 60% filler
I hope this design be helpful for those with limited use of their hands.
