Top Fin CN10 Corner Filter Suction Cup Stand-off

thingiverse

My betta fish recently got trapped between a CN10 filter and the glass and died. It really sucks... but I hope this modification can save other fish out there. In response I designed a spacer to ensure that the CN10 filter is 12mm or 0.5 inch away from the glass so no small fish can get trapped between and die. The space would still be a hazard for medium or larger fish, but this is really meant for betta. This is designed for the ubiquitous air line suction cups found on eBay/ Amazon that have the little white clips.
