Aquarium air and power Routers

thingiverse

A clip to force wires and pipes for thermostats, filters, lights and airstones into a snug U shape over the tank edge. If mirrored in your slicer you can print left/right versions and glue them together for routing multiple items into filter boxes etc. A small slot is incorporated in the posts to allow small cable ties to secure everything if needed, but in practice I have only found this necessary on one particularly awkward cable setup. Small version has a 9mm gap (tank edge width), while the bigger version gives you twice as much, 18mm of space for easy routing. I shopped around and found filament from Fil-a-Gher that's certified 'Food Safe', which seems like a sensible precaution with my fish, though I love cheap but good no-name filament most of the time.
