Wrench for aquarium bulk head (Glass Holes)

thingiverse

A high-quality wrench is needed to securely fasten a 1 1/2-inch aquarium bulkhead, particularly one designed for use with Glasshose overflows. To produce this wrench effectively, it's recommended to print it using PLA plastic and add supports at approximately 70% infill. This design also proves to be very effective on the EShopps medium overflow box.
