If you have a Bosch dishwasher with a third rack for cutlery, and it has the folding tines on either side, you may have found that those tines won't stay upright. As designed, the folding tines don't have enough support, causing the plastic to sag over time. When it sags, the catch that's supposed to keep the tines upright no longer catches.
This bracket provides mid-span support for the folding tines, allowing the catch to work properly.
You'll have to carefully flex the tines upward to slide this bracket underneath. If your tines are brittle and break, or if you find that the OEM tines are a bit too short to properly engage the slots in your rack, you can print a replacement such as https://www.printables.com/model/562208-bosch-dishwasher-separator-remix.
CAUTION: You must use a filament that's safe for high temperatures and chemical exposure. Automatic dishwasher detergent is caustic and will dissolve many plastics. While modern Bosch dishwashers don't have electric drying coils, they do heat water to 161°F (72°C) or more. If you use PLA, the part will fail rapidly and may clog your dishwasher's impeller when it falls off. I recommend printing the part from Fiberlogy CPE HT, which is dishwasher-safe in all regards. CPE HT doesn't require an enclosure. If you don't want to buy CPE HT, use a high-quality PETG and check it often for signs of deterioration.
