Toronto Blue Jays Chain Necklace/Pendant/Keychain

I designed this for my kids for a special Blue Jays event at school — I wanted them to have something fun to wear that wasn’t ridiculously huge. This pendant ended up being the perfect size: 2.5” (68 mm) in diameter, compact but still detailed enough to stand out.

The coolest part is that the logo is accurate on both sides. It prints flat on the build plate as a mirrored logo, and the top features raised elements (1 mm thick) that give it a nice 3D look. The design makes it versatile — you can wear it as a pendant necklace, or even clip it onto a backpack as a keychain. It will always look good, no matter which side faces out, it looks correct.

The chain is built from three types of link pieces that snap together perfectly without glue. It includes 60 regular links that slide smoothly into each other, 2 connector links with openings for the pendant, and 1 double-ended link that connects both sides behind the neck. The result is a flexible, durable chain that prints efficiently and feels great when worn. The chain is set to print by object, so even with two colors, it completes all links of one color before switching filament — faster print, less waste.

I used 61 links total for mine, which fits comfortably over my head and sits at a good length for both adults and kids. I’ve included 69 links so you can adjust the size however you like — shorter for kids, longer for adults.
