Since I’m into anything storage, I have a few collapsible plastic gaylord boxes. At some point, one of them had something heavy dropped on its lid that caused a crack that would then let water leak in, if it were outside. This was past glue of epoxy, so I tried a plastic bumper repair kit. so far I’m pretty happy. I’ve trimmed off the extra legs, but I’ll need to sand it down just a little. When that’s done, I think I’ll drip in a little bit of Cyanoacrylate glue. just to make sure its as watertight as it can be. The lid is 80$ plus shipping, the https://www.amazon.com/dp/B08BJSXW7R?psc=1&ref=ppx_yo2ov_dt_b_product_details kit was 24$ on amazon.
