Tippet Gauge

Tippet is teeny tiny monofilament for fly fishing. If you're lazy like me, sometimes you leave tippet or a leader attached to your line and then you forget what diameter it was. Or maybe you need to measure the size of that guppy you just caught. Either way, this will help. Just stick the filament in until it doesn't fit in a slot. The little hole is for a key ring. If you don't fish but just need to measure skinny things, 0X = 0.011", then subtract 0.001" for every NX. This goes down to 7X = 0.004". I checked the one I printed (P1s, PETG HF, 0.4mm nozzle) against my tippets, and I am impressed that it printed within 0.001" tolerance. It might be even better with a 0.2mm nozzle.
