Every pick is generated locally in your browser: the geometry, the preview, and the STL, OBJ and 3MF exports never touch a server. The only network request the tool makes is loading the three.js preview library from a CDN — your design itself is never uploaded anywhere.

Shapes a player recognises

Ten templates, each built from the real-world dimensions of the pick it is named after: Classic (30.7 × 25.9 mm), Classic pointed, Small jazz (25.4 × 21.6 mm), Large jazz, the big 32 mm triangle with three playable tips, a rounded triangle, a short thick pick, a teardrop, a wide-shouldered sculpted shape, and a wave-edge shape with a wavy strumming edge. They are not decorative approximations — the outline is generated the way a pick is actually specified, from three corner radii and the arcs between them.

Tune the specs that change how it plays

Tip radius is the number that decides the sound, and here it is a slider in millimetres: under 2 mm gives you a sharp jazz-style attack, 5 mm and up is a rounded classic strum. Then set shoulder radius, back radius and edge bulge, or drag the handles straight on the to-scale top view. Thickness runs from 0.4 to 4 mm against a gauge ruler marked with picks you already own — 0.88 mm tells you it is a medium pick. Pick an edge profile (square, chamfer, rounded bullnose or a one-sided speed bevel) and a magnified cross-section shows exactly what the string meets, drawn against a .010 high E for scale. Add a scooped thumb dish, one of five grip textures, real through-holes, and raised lettering with your name or initials. Switch the top view to 1:1 actual size and hold a real pick against the screen, or ghost the Classic shape behind your design to compare.

Built for real printing, not just pretty previews

Every change updates a live design check that knows your nozzle size: it flags a tip too fine to resolve, lettering thinner than one extrusion, texture deeper than half the pick, a pick only three layers thick, a square edge that will catch the strings, and filament choices that will not survive the gauge you picked — with concrete fixes, not just warnings. Filament estimates cover weight, print time and material cost for PLA, PETG, ABS, nylon, PCTG and TPU. Export one pick or a plate of up to 24 in a single STL. Picks print flat on the bed with no supports, and the exported mesh is a closed, manifold solid that Cura, PrusaSlicer, OrcaSlicer and Bambu Studio all accept.

Frequently asked questions

Do I need an account?

No. No sign-up, no install, no limits — design and download as many picks as you like.

What file formats can I export?

Binary STL, OBJ and 3MF for printing, a PNG snapshot of your design, the 2D outline as SVG and DXF at true size in millimetres for laser cutters and CNC, and the parameters as JSON. A share link encodes your exact design in the URL so you can send it to a friend.

What thickness should I choose?

Under 0.8 mm plays thin and flexible — bright attack, great for strumming. Around 1 mm is the all-rounder. Above 2 mm is rigid and loud, preferred for precise single-note work. The gauge ruler names the closest familiar pick as you drag, from extra thin at 0.46 mm through light-medium at 0.73 to small jazz heavy at 1.38 and an ultra-thick at 3.0.

What tip radius should I use?

Under 1.6 mm is a needle tip — pinpoint attack and fast lines. 1.6–2.6 mm is small-jazz territory: articulate, good for lead. 2.6–4 mm is the all-rounder. Above 5 mm is a classic strumming round. The tool describes the feel of whatever radius you land on.

Which edge bevel should I print?

Rounded releases most smoothly off the string and forgives a sloppy picking angle. A chamfer is crisper and more articulate. A speed bevel is heavy on one face and barely there on the other, so it glides one way and bites the other — set up for a right-handed grip, flip the pick for left. Square is fine on thin picks and catches badly on thick ones.

Can I put my name on it?

Yes — up to 14 characters of raised lettering on the grip, which doubles as texture under your thumb. The design check warns you if the thinnest stroke drops below one nozzle width.

Can I print a batch?

Yes. Choose 1, 3, 6, 12 or 24 copies in the toolbar and the export arranges them across the plate in one file.

Will the STL work in my slicer?

Yes — Cura, PrusaSlicer, OrcaSlicer and Bambu Studio all accept the exported STL and 3MF files. Print flat on the bed, 0.12–0.2 mm layers, no supports. Nylon and PETG survive pockets better than PLA.

Is anything uploaded to a server?

No. Geometry, preview rendering and file exports all happen client-side in your browser. Nothing you design is sent anywhere.
