Fish Tank Cable Guide – Tidy & Protect Cables on Rimless Aquariums

A simple cable guide that keeps aquarium cables neat, controlled, and protected as they run over the rim of the tank. It tidies up the messy tangle of probe, heater, and pump leads that usually drape over the glass — giving your setup a cleaner, more finished look while protecting the cables from kinks and chafing.

Designed for rimless aquariums with 10 mm glass, with the width easy to adjust in your slicer or CAD if your glass is a different thickness.

✅ Features

• Routes and tidies cables over the tank edge

• Protects cables from kinks and abrasion

• Cleaner, neater aquarium appearance

• Works for temperature probes, heaters, pumps, and similar leads

• Width easily adjusted for other glass thicknesses

• Original design

💡 PETG is the sensible choice around water and humidity. If your glass isn't 10 mm, adjust the guide width to suit before printing.
