birthprint
Personalised baby birth letters, ready to 3D print
A big first letter with the baby's name in script, and the date, time, length and weight on little badges, plus decorations like animals, clouds and hearts. Every piece is its own coloured insert that presses into a pocket in the letter.
For new parents, grandparents and makers who sell nursery keepsakes.

What you can make
The name and the details
The full name in a script font over the letter, and badges for the date, time, length, weight and, if you like, the place of birth.
Decorations to choose from
Animals, clouds, stars, hearts, footprints and more, in sky, forest, sea, safari and nursery sets, or upload your own SVG.
Inserts that press in
Each piece sits in its own pocket with a 0.2 mm gap all round and a 0.4 mm bevel underneath, so it presses in by hand; a small drop of glue holds it for good.
Arrange it your way
Drag, scale and rotate every piece on the letter; the app checks that everything fits your bed and nothing is too thin to print.
Colours made simple
One file per colour with every insert of that colour laid flat, and the colour change for raised badge text already set.
A README with every height
Which part prints in which colour, the height of every colour change, and an estimate of filament and time.
