What is a 3D letters generator?
A 3D letters generator is a tool that turns typed letters into printable 3D shapes with real depth. Kenerate's free generator runs in your browser: download a word as one STL, or A–Z and 0–9 as separate STLs in one ZIP. For free-standing letters, make the depth about a third of the height.

FAQ
3D Letters Generator questions
8 questions
How do I get 3D letters A to Z?
Choose a font and size, then click “Download A–Z + 0–9 as separate STLs”. You get a ZIP with 36 files, one per letter and digit.
Link to this answerWhat size should free-standing letters be?
At least about 30 mm tall, with a depth of roughly a third of the height, in a bold font. Thin or script letters need a base.
Link to this answerWhich fonts are best for 3D letters?
Heavy, simple fonts: Luckiest Guy, Archivo Black, Bebas Neue, Anton, Russo One or Alfa Slab One.
Link to this answerCan I get lowercase letters?
Type them into the text box and download. The alphabet pack contains capitals and digits.
Link to this answerHow do I draw 3D letters by hand?
Write the letter in outline, copy the outline a little up and to the side, join each corner with a short line, then erase the hidden back lines and shade one side. The 3D view here is a handy reference for the angle.
Link to this answerHow do I draw 3D letters with shadows?
Draw the 3D block letter first, then pick where the light comes from. Shade the side faces that turn away from the light darker than the front, and add a flat cast shadow on the ground offset away from the light. Keep the same light direction for every letter in the word.
Link to this answerCan I sell the letters I print?
The bundled fonts are open-licence (OFL / Apache 2.0) and allow use in printed products. For uploaded fonts, check their licence.
Link to this answerIs anything uploaded?
No. The letters are built in your browser.

Stand-up proportions, printable strokes and how to draw 3D letters.
On this page
Proportions that stand
A letter stands when its footprint is wide enough for its height. Depth of about a third of the height works for bold fonts; letters like I, J or T benefit from extra depth or a base. Thin strokes under about 0.9 mm are fragile when printed [11].
Drawing 3D block letters
The classic method: draw the letter as an outline, repeat it offset diagonally, connect matching corners, then remove the lines that would be hidden and shade the side faces. Keep the offset direction the same for every letter so the word looks consistent.
Fonts and licences
The fonts here come from Google Fonts under the SIL Open Font License or Apache 2.0 [19], which allow them in printed and sold objects.
