25 useful 3D printed gifts people keep, with the sizes that make them work
6 October 2026
A printed gift has one job after the wrapping paper: get used. Most of the ones that end up in a drawer fail on a number, not on the idea. The letters are too thin to survive a key ring, the stand is cut for a phone without its case, the jar lid binds after a week. Below are 25 gifts from the model library that I'd hand over myself, each with the dimension that makes it work. Every one opens in its generator, so you can change the name, the size or the text before you print.
Names and letters
A name keychain is the classic, and the keychain generator does it in six fonts. The Zosia keychain uses the contour style: 16 mm script letters inflated by 3 mm into one fused piece, 3 mm thick, with the ring hole in the first letter. Under 12 mm the contour gets thin bridges between letters, so stay above that.
Names are also where the generator embarrassed me. Until 24 September, four of the six fonts silently dropped accented letters. Ż, ą, ł and ó are stored in those font files as a base letter plus an accent, and my text code only drew plain outlines, so the composite letters vanished from the part. The coaster generator's own default text, a single Ż, failed outright with "Could not draw the artwork". On a test line of Polish at 30 mm, the comic font produced 1,552 mm² of letters where 3,711 belonged. About a sixth of the visitors are in Poland, so plenty of those names were Polish.
In Lobster, the handwriting font, neighbouring letters overlap, and every overlap got cut out of the stroke, leaving a notch at each join. Fuzzing found 8 broken keychains in one run. That run now finds 0.
If a name is too personal, a key tag with one word works for anyone. The DAD tag is a pill with the letters as a flush two-colour inlay, and the same file says BIKE, HOME or SHED once you change the text. Print it in PETG, it lives in a pocket with keys.
A monogram coaster is the next step up. The round A coaster is 95 mm across and 4 mm thick, with a raised ring that catches condensation, and it prints flat in about 20 minutes. For a wedding there is a two-initials version, and a set of six is a single afternoon.
Bigger letters go on a door. The house number sign has 60 mm characters on a 3.6 mm plate with two countersunk screw holes, and the welcome sign does the same in script at 24 mm, held up with tape. Single-colour printer? Use raised letters, or swap filament at the layer where the inlay starts.
Kitchen
A cookie cutter is the gift that comes back as cookies. The MAMA cutter and the LOVE cutter are 100 mm wide with a stepped blade ending in a 0.7 mm edge, plus a flange to press on. The cookie generator takes any word or a drawing.
Spice jars get refilled for years. The 55 mm spice jar is 70 mm tall inside with a coarse 3-start thread, so the lid closes in under a turn. A set of four on a shelf beats one big gift. For tea or sweets, the 65 by 45 mm tin adds a TPU seal washer under the knurled lid.
A wine bottle cooler is the one that surprises people. The 200 mm cooler is a 20-lobe vase-mode cylinder, 100 mm at the base and 110 mm at the top, so a bottle and some ice fit. Vase mode means one continuous wall and nowhere for water to leak through.
Desk
A phone stand fails when it ignores the case. The desk stand holds a phone 11 mm thick, case included, at 62 degrees, and the stand generator changes that thickness in one field. The e-reader stand is the same idea for 8 mm and 110 mm wide, and the tablet stand cradles a 10 or 11 inch tablet at 60 degrees in 120 mm.
The pen cup is the quick one. The six-point star cup is 100 mm tall, prints in vase mode, and costs very little filament.
A headphone hook clears a desk. The J hook reaches 50 mm with a 20 mm wide arm and screws under a desk or shelf, so the headband hangs instead of sitting on the keyboard.
Boxes that open
A glasses case with a living hinge is my favourite on this list. The clamshell case is 160 by 72 by 44 mm closed, one piece, and the hinge is a 0.6 mm film of plastic. In PETG it folds hundreds of times. In PLA it cracks. PETG only.
A print-in-place box is a small magic trick. The stash box prints flat and open in one part, with a 7-knuckle barrel hinge and a pin printed inside it, then snaps shut on a cantilever latch. It is 90 by 67 by 42 mm closed. The sewing kit box uses the same hinge at 110 by 75 mm.
For someone who carries things, the EDC rugged box is 100 by 70 mm inside and 42 mm deep, with a print-in-place hinge, a snap latch, bumpers and ribs, and no hardware to buy.
For a card player, a deck box sized to their deck. The Commander box holds 100 double-sleeved cards under a magnet lid. Count the sleeves before you print.
Light and plants
A lithophane is a photo you can only see with a lamp behind it. The photo becomes plastic thickness, 0.8 mm where it is bright and 3 mm where it is dark. The lithophane post has the numbers, and a 100 mm plate is an overnight print.
A bud vase for one stem. The 140 mm gaussian vase narrows from 55 to 28 mm and prints in vase mode in one wall. Taller and showier, the star lantern is 240 mm with a 150 degree twist. Both slice in spiral mode without fixes, because the vase generator refuses shapes that would not.
A succulent pot gets watered, which means it needs holes. The 80 mm pot is 10-sided with 3 drainage holes. Put it on a saucer, or the windowsill pays for it.
Last, for anyone who sells what they make: a stamp. The made with love stamp is 70 mm wide with 1.6 mm of relief and a knob handle. Print it in TPU and it takes ink from a pad like rubber does, in PLA it presses into clay. Its letters read backwards. The imprint doesn't.
