I'd love some advice on repairing or replacing this bamboo cup lid, which has lasted around 5 years otherwise!

I've thought about doing a kintsugi type repair, since I still have the broken pieces:

However, most kintsugi kits I've seen for sale online are either pretty expensive or not meant to be in contact with food. I'm cautious about using a cheaper epoxy for that reason as well -- I'm not sure how concerned I should be about chemicals leaching into my coffee even after it's cured.

Maybe I should just look for a replacement lid online? This one is about 9.5cm across, but I'm not sure they come in standard sizes
