Fisherman’s KitCard – Full set Birthday card

Why I Like It

This is one of my favorite prints for the sheer audacity of the concept: a fully functional nano fishing kit printed on a card the size of a birthday card. We’re talking hook holders, line wrap, a small sinker cavity, and everything arranged so it fits flat in a wallet, notebook, or envelope. And yes — it works. This is not a novelty. People have caught fish with gear from prints like this.

The “birthday card” framing is actually genius from a gifting standpoint. Print it, load it with real fishing line (you supply that — the print handles everything else), tuck it in a card, and you’ve given someone a legitimately useful piece of gear that cost you almost nothing and took about an hour to print. It’s the kind of gift that makes people go “wait, this is real?” and then actually use it on their next camping trip.

For print settings, precision matters more than strength here. 0.15mm layer height, 3 walls, 20% infill — you want clean geometry on the hook slots and line wraps, not raw mass. PETG is the right call: it’s smooth, slightly flexible (which helps with the line wrap tension), and holds up to moisture better than PLA. Print flat, no supports. Give yourself a few tries to get the tolerances dialed — the satisfaction when the line seats cleanly in the holders is worth it.

What Filament Should You Use?

Here’s a quick breakdown of the three most common filaments for EDC gear so you can pick the right one for your setup:

TL;DR: Use PETG for most EDC prints — easy to work with and tough enough. Use ASA if the piece will live outdoors or in direct sunlight. Use ABS if you need maximum rigidity and heat resistance and have an enclosure on your printer.
