This compact chainsaw chain locker is designed to safely store and transport spare chains without the usual hassle of tangled loops or chains getting banged around in your saw case. The box comfortably holds up to two 20” chains, and can fit additional chains if they are shorter, making it a convenient way to bring a few spares with you into the bush.

Instead of dealing with the infamous “chainsaw chain knot”, this locker keeps chains neatly contained and protected so they’re ready to go when you need them.

The bumps in the base of the case are designed so you can wrap the chains around them to help hold the loops in place. A corresponding bump on the lid helps prevent the chains from lifting up and coming off the lower bumps, which helps keep them organized and prevents them from tangling together while the case is closed.

The model includes three lid options so you can organize your chains however you like:

• Sharp Chains
• Dull Chains
• Blank lid (no label)

Just print one lid per base, you don't need all three.

The design prints well in durable materials. I’ve successfully printed it in ABS and PC, and both versions have proven very strong and capable of handling a typical trip in the bush alongside a saw, fuel, tools, and other gear.

The included print profile uses a small amount of support, but with my basic printer settings on a Bambu X1C, the supports worked great and came off easily with minimal cleanup.

This design is based on the excellent Rugged Storage Box (Parametric and Customizable). Huge thanks to cephalopodsquid for creating such an amazing and versatile model to build from.
