See-through fish hideout

I have fish that like to hide, so I rarely saw them.  I decided to design a hideout for them that allows me to see them through the glass.  It has a flat back for the gravel to cover to weigh it down.

Printed in PLA.  Please print in a material that is safe for your fish or coat in epoxy before putting in your tank. 

20-50% infill

Use supports on build plate only.
