Swimming Lap Counter
thingiverse
This was based on a Abraham Kurtzweil's (@bluelego) life counter https://www.myminifactory.com/object/3d-print-magic-the-gathering-life-counter-2608. I needed a simple device to track sets at the pool. My version has a screw on cap and and an arrow. The ability to tighten it makes it easy to adjust poolside.
