This is a simple kitchen brush and sponge holder I designed to fit my regular accessories I had lying around. It can hold: 

• A typical kitchen sponge of approx. 12cm x 7cm 
• A sink brush with 5cm diameter (holder is 6cm so an even larger brush can fit)
• A Wettex sponge towel (if wet it can fold any way you like)
• A typical dish washer soap bottle (An AVA bottle is used, very common in Greece but I'm sure a lot of other bottles can fit)

The sponge holder has vertical small cones so that the sponge can dry quickly. Excess water can run out from the front. All other holders have drainage holes on the bottom for this specific reason.

It is a ridiculously easy design not because I am a fan of any simplistic art movements but because my CAD knowledge is awfully poor. This is designed in Tinkercad, that's how far I can go. So, please, if you have better skills than I do, I would love to see a much prettier remake! 

Model size is 250mm x 150mm in order to fit on my Voron. You can resize it as much as you can in your slicer. Height is 120mm. 

Update: I also uploaded a divided version of the original design. I split the front three compartments from the dishwasher holder so that they can be printed separately and glued afterwards. Thus, front part is 150mm x 160mm x 100 and dishwasher part is 150mm x 90mm x 120mm and as a result both can fit on a Prusa MINI! 

Hope you enjoy it!
