This 3D-printed insert is designed to fit perfectly into a 2x3 Gridfinity bin, solving a common storage frustration. While most hex key sets can fit into a standard 2x3x9U bin, their ergonomic curves often lead to a messy, difficult-to-access situation where you're constantly fighting to get them in and out.

My goal was to create a more organized and user-friendly solution. Instead of designing an entire bin, this insert offers universal compatibility with most standard 2x3 bins, giving you the flexibility to choose your preferred bin height.

The result is a simple, drop-in insert that neatly aligns and securely holds your hex key set. It's designed for effortless access, featuring a clever push-tilt mechanism: simply press down on one end, and the other side pops up, allowing you to easily grab the desired key. This design not only satisfies my own OCD but makes your tools readily available.

I've included two versions for your convenience. The original solid version, while functional, wasn't stackable with a 9U bin. To address this, I developed the 9U stackable version, which features strategically placed cutouts. These not only allow for stacking but also significantly reduce print time and filament consumption (by half!), without compromising functionality. The solid (no hole) version is also included if you prefer.
