4 Toothbrush Bicycle Chain Cleaner

thingiverse

I've been brainstorming ways to repurpose toothbrushes as a functional chain cleaner for years now. Initially, I envisioned a spring steel holder that folds like origami to hold the handles in place. However, when I got my hands on a 3D printer, I decided to rethink the design entirely. The result is a single-piece design that doesn't require any retainers and can be easily held in one hand while spinning the crank. This innovative solution makes quick work of chain cleaning tasks. It's worth noting that I've since discovered similar designs that incorporate three or four toothbrush heads, but they weren't my inspiration nor did I copy their ideas. Instead, I created a unique solution that meets my needs and preferences.
