Maxspect Bio-balls Holder

Here is my custom-designed Bio Ball Holder, specifically for Maxspect bio balls filter media. This cradle holds 36 bio balls, perfectly accommodating one 1kg box (approximately 40 balls). Measuring 160.8mm in length, 126mm in width, and 117mm in height, it features five small feet on the underside to ensure optimal water flow. Enhance your filtration system with this efficient and space-saving solution. On the underside are holes that run the length of the pins and can be filled with thin super glue to add strength. Should be printed with PETG!!!
