About this 3D model

I present to you a Electric Box Key, it weights only 3.17grams, and has a hole for a rope so you can hang it somewhere or tie with some other keys. The hole might get clogged by a little piece while printing, but removing it should be easy with a small screwdriver and a little push. Recommend printing with 100% infill for max durability, increases the filament use to only 3.62g. Might need slight scaling to meet your needs, mine fits perfectly.
