Fillable Adjustable Dumbbell (DIY / 3D Printable)
This is a fillable, adjustable dumbbell designed for home use and easy 3D printing.
Instead of fixed weights, the dumbbell can be filled with common materials like sand, rice, lentils, or small pellets, allowing you to customize the weight to your needs.
The design uses:
Hexagonal ends to prevent rolling
A hollow body to reduce print time and material
A friction-fit removable cap for simple filling (no fragile threads)
This model was designed to be printer-friendly, minimizing supports and maximizing strength through proper orientation.
