4" Aquarium Sock Pre-Filter holder

thingiverse

My brother needed a mount for his 4" filter sock for his aquarium. I whipped this up and it seems to be working for him. Designed to hold a 4" pre-filter sock. I included two sets of holes that accept 1/4x20 screws to mount it to the side of your tank. The holes are tight but once you thread the screws in they will cut threads and should hold well. Filter mount's inner opening is 3 3/4" in diameter. The bracket is 2" tall with a 1" wide opening.
