Small water tray for OSTBIT plate holder to collect all water from plates or lids. Designed to easy print by 0.4 nozzle and could be printed vertically (on side) for stronger "ears snaps" or on bottom side to get better surface. I have printed both ways, and found, that in case of PETG or ABS filament, printing on side (without supports) will be tricky due thermal deformation. So, to get better surface it could be rotated to bottom flat surface and printed with support for ears only.
Also, due IKEA OSTBIT wood assembly have pretty non-stable tolerance it could be some small gaps on sides or near snaps.
