Chaeto tumbler, horizontal. Reef tank. Macroalgae.

thingiverse

I wanted to put a chamber for Chaeto in my sump as a mini-refugium. Though I wanted to illuminate it from the side, gotta be different I guess. Ill check back with how it works. Resize to your needs in your slicer. I sliced this with Zero top and bottom layers, the first 2cm I used 10% infill, the rest 0% infill, that way I can fill the cavities with rock rubble.
