Swimming buoy (source file included)

thingiverse

Made a buoy designed to stabilize the legs while keeping them from kicking. The buoy was crafted from PLA, but it began leaking, prompting me to apply a coat of PlastiDip, a type of rubberizer. Despite still leaking, the buoy functions perfectly. To achieve optimal results, I employed an almost-zero infill percentage. However, I caution against using too little infill, as it can compromise the top layer's integrity and increase the likelihood of collapse when submerged. A 5% infill rate worked well for me; a slightly higher percentage would have been even better. Considering the buoy's purpose, ABS and vapor smoothing might be a more intelligent choice. A SolidWorks file is included for anyone who wishes to modify the leg size (my legs are quite slender).
