Aquarium Bulkhead Strainers (15mm BSP Thread)

thingiverse

There are three types of strainers available: a 5x5mm grid model, a 2x2mm grid model, and a no-grid version with a 3mm lip that allows users to attach a custom-made SS mesh. This feature is particularly useful for tanks where specific mesh sizes are required. The strainers come equipped with a 15mm BSP thread on the end, designed to be used in conjunction with a 15mm female bulkhead. These components can be sourced from online retailers such as Bunnings, which offers a range of tank access outlets suitable for aquarium use. These strainers are originally designed for use in aquariums but can also be applied in other contexts where filtration is necessary. In practice, users have found the 5x5mm grid model to be effective for larger adult fish like Apistogrammas, while the 2x2mm grid model is better suited for smaller species such as Celestial Pearl Danios. A no-grid version of the strainer can be used in conjunction with a super-fine SS mesh, making it ideal for use in fry tanks. When printing these components, users have found that using a variable resolution setting can significantly improve print quality. For example, printing at 0.2mm resolution for the bottom half and 0.1mm resolution for the threads has been shown to produce better results than uniform 0.2mm resolution across the entire component. This technique can be achieved using software such as Simplify 3D's variable settings wizard.
