Tired of your BCD's fiddly little pull balls being impossible to find in your heavy dry gloves? Struggle no longer with these handy 3D printed replacements!

With a flattened base for easy printing and a rounded, ribbed design for grip, print these at full infill to minimize their buoyancy and simply tie them in place of your existing pull handles. The design is fairly simple, so feel free to edit the scad file if you want a larger/smaller design or if you need to adjust the hole sizes for your particular pull string
