Aquarium Snail Shovel configurable

thingiverse

Here's a configurable version of a snail shovel that can also be used as a base for cat litter or similar applications. I created this design originally in FreeCAD and have since recreated it in OpenSCAD, allowing users to easily modify parameters and adapt the design to their specific needs. I personally use this snail shovel as a tool to filter out unwanted snails from my aquarium floor: the snails remain inside while the gravel passes through. However, for this system to be effective, the ground material must be smaller in size than the snails you're trying to catch.
