I designed this because the gap between my sink and the back wall was constantly a mess, especially after washing cutting boards. This is a two-piece drip tray that catches water and directs it back into the basin. It is a slim 8cm deep, so it fits in those narrow spaces where standard mats usually won't. It works especially well for propping up wet cutting boards to air dry.

Overview

The model consists of two separate 25cm wide sections. When placed together, they cover a total width of 50cm. Drainage angle is controlled by the risers.

Customizable Risers

While the trays are a fixed size, the risers are fully customizable because every sink has a different rim height.

• Default Riser: 50mm length, 8mm front height, and 10mm back height
• Configuration: You need to print 3 risers per tray (6 total for the full setup) to ensure the tray is stable and doesn't sag
• Customizer: If the default height doesn't clear your sink edge or you want a steeper slope, just use the MakerWorld Customizer

Assembly

Don't reach for the glue immediately.

1. Place the trays behind your sink and slide the 3 risers under each one.
2. Move them around until the tray is stable, especially if you're leaning heavy boards against it.  Check that the water actually flows forward.
3. Once you've found the right spots, use a bit of super glue to fix the risers to the bottom of the tray so they don't shift during cleaning.

Recommended Print Settings

• Material: PLA is fine if you don't have it in direct sunlight. PETG or ASA otherwise
• Walls: 3

If you end up using this for your kitchen, let me know how the fit is. I'm curious if the 8cm depth works for most people's cutting boards or if I should look into a wider version later.
