Little gridfinity "bin" for holding a set of Pinecil heat-set inserts and tip.

Comes in two variants, one “solid” and one pass-through. The pass-through is good if you mount the gridfinity to a wall (such as with my Skadis board mount) or some other system where you can have the tip pass through it. If you're not doing this, the solid variant just has the pass-through hole filled in, same as the other holes.
