Wood Stump Tunnel for Aquarium

thingiverse

I remixed daandruff's design as a aquarium fish tunnel. You can scale it for bigger fish. I strongly recommend to print it with PETG or ABS. PLA can dissolve in water over time. (I used brown ABS) You can print it with %100 infill or you can place something heavy on the top of stump (stone in my case). I used support for better arches but you can print it without support if your machine capable of that.
