Stackable BB Waterfall

thingiverse

A stackable BB waterfall/fountain/marble run design features endless potential due to its height-stackable center piece. The unique top spiral and bottom cup for collecting BBs provide numerous expansion possibilities, including new center pieces with internal and external BB flow or branching into adjacent columns. BBs offer cost advantages (6000 for $10) and small size (hold hundreds in hand), enabling flexible designs and a soothing sound. This product is perfect for rain lovers without spousal disapproval. The bottom piece, cup, and center piece print effortlessly without support, while the top piece may require single-support printing. An alternate bottom piece with a sliding drawer is also being developed but requires support. Key specifications include a main cylinder width of 15 cm, ramp width of 12 mm, ramp lip height of 3 mm, and stacked/non-stacked heights of 5/6 cm respectively. A Python script for gedit integration with OpenSCAD would be useful, but no such plugin is currently known.
