Reef Mower

A handy tool for stripping hair algae from an aquarium. Just assemble the sticks and joints to the length you need. You can gently remove long hair algae by sticking the blade into it and twirling.
A rough finish is more effective, but harder to clean; smooth finish is less grabby, but easy t clean so pick your poison.

I recommend either solid or high fill for strength. I used brims since the bed contact is pretty small on all the parts. Assemble with glue that's suitable for your filament.
