Fluval Chi Replacement arm

thingiverse

I bought a used Fluval Chi 5 gallon fish tank on craigslist. Was missing the arm that houses a magnet... took me about a year to figure out the light was in fact *not* broken! This is a not-so-pretty-but-fully-functional replacement arm that has a 2.5mm hole in it for a rare earth magnet to turn on the light. Works great for me.
