MTB chain cleaner

thingiverse

This thing uses four disposable toothbrushes, which I picked up for a steal at 12 Euros on eBay. The heads of these brushes are clipped off and inserted into the main body - there are three of them - as well as the sliding part itself. The clamp is secured to the main body using two M4x16 screws that have been directly tapped into the plastic. Once this is done, it can be pushed onto the bicycle chain and the slider can be inserted afterwards. Now, you can start turning the crank, which will cause the chain to get brushed from all four sides.
