Keycap guide
How to choose a 3D printed keycap
Compatibility, daily typing, heat and cleaning — the four things that decide whether a sculpted keycap is a joy or a nuisance, answered before you order.
First question: does it fit?
Everything we make uses a standard MX-style cross stem. That covers Cherry MX and the clones most boards ship with today: Gateron, Kailh, Outemu and their relatives. Pull any keycap off your board — if you see a plus-shaped stem underneath, these will mount on it.
They will not fit low-profile Choc switches, Topre barrels, or a laptop keyboard. No adapter fixes that; the stem is the only part that matters and it is printed to one specification. If your board is a normal mechanical keyboard bought in the last few years, you are almost certainly fine.
Second question: where should a sculpted cap go?
The sweets and animals — cat paw, cupcake, burger, chocolate bar — are shaped like comfortable typing keys: flat-ish top, rounded edges. The plate-style sets that replace a whole row of nine are the same height as a uniform keycap profile.
The one honest caveat: the tallest sculpted designs have more height above the stem than a stock cap. On a standard 19.05 mm pitch they do not collide with their neighbours, but if your board has an unusual bottom row or you rest your palm on the case, put the tallest piece on a key you rarely press — Scroll Lock exists for exactly this.
Third question: what is it made of, and what hurts it?
PLA, printed solid in the stem area. Two rules follow from that. First, heat: PLA softens around 60 °C, so a keycap is fine on any desk and ruined on a car dashboard or next to a laptop exhaust vent. Second, cleaning: a dry brush or a barely damp cloth. No dishwashers, no solvents — the surface finish is part of the print.
Wear is the good news. The legend on a printed keycap is not paint or a dye-sub layer — it is the geometry of the print itself. There is nothing to rub off, which is the main reason sculpted caps outlast the printed ones they replace.
Single key or nine-key set?
A single sculpted key is an accent — one cat paw on the Esc key says more than six of them. The nine-key sets exist for people who want the whole row: a strawberry patch, a blueberry grid, a tray of tomatoes. They are printed as one plate with nine caps, snapped apart and cleaned before shipping, which is why a set costs noticeably less per key than nine singles.
Not sure which? Start with one keycap. It is the cheapest way to learn whether the material and the profile suit your hands, and it is the piece guests actually notice.
Keycap questions
Will a 3D printed keycap fit my keyboard?
If your switches have an MX-style cross stem — Cherry MX, Gateron, Kailh, Outemu and most others — yes. It will not fit low-profile Choc switches, Topre, or a laptop keyboard.
Can I type on them every day?
Yes. The tops are printed flat enough for a fingertip and the detail is raised rather than sharp. For very tall designs, use them on keys you press less often.
How do I remove one without breaking it?
With a wire keycap puller, straight up. Fingernails or sideways leverage put stress on the stem that the design is not meant to take.
Do the designs fade?
No. There is no printed or painted layer — the pattern is the geometry of the print itself. What you see is the same plastic all the way through.
