Plastic rivets that hold joints together on PiCrawler

I accidentally broke those little plastic rivets that hold the joints together so does anyone know where I could order more? TIA

2.8mm wide and 7.3mm long

You can buy it on Amazon and just choose the rivet model you need.
Here is the link we provided.

Awesome. Thanks for quick response. For PiCrawler I believe the size is 3.0 x 6.5mm or ‘3065’.
