FAQ

Frequently asked questions

Everything you need to know before you start designing.

What are the markers made of?
All markers are printed from food-safe, biodegradable PLA. You can choose between 4 finishes — matte, silk, marble and wood — in 10 soft nursery colours.
What size are the markers?
Markers are about 8–10 cm across and 3 mm thick, with text and patterns raised 1 mm for a tactile finish. The size is ideal for monthly baby photos.
Can I print the STL files myself?
Yes. The STL files are high-poly, watertight binary meshes that print without supports on any FDM printer. Slicer profiles for Cura and PrusaSlicer are included.
How does ordering work?
Design your set in the configurator and send an inquiry with your email — no payment online. We reply within 24 hours with payment and delivery details, or with your STL files.
Can I get both printed markers and STL files?
Of course. Choose the printed product in the cart and add the STL files of your set as an extra — or order just the files and print at home.
For home printers

How to print at home

Every file is validated automatically before download — watertight mesh, bottom on Z=0, no supports needed. Three steps to a keepsake.

Download STL or 3MF
STL is universal for every slicer. We recommend 3MF for Bambu/Orca Studio — the text is already assigned to a second filament for two-colour printing.
Set up your slicer
Layer height 0.2 mm, infill 15 %, supports off — the model doesn't need them. PLA, 0.4 mm nozzle.
⬇ Download ready-made profiles (PrusaSlicer + Cura)
Print
Print raised text face-up. For engraved text, flip the model face-down on the bed and swap the filament colour for the last layers for a two-colour effect.
