Layeria: STL & 3MF 3D Viewer

Layeria opens STL, 3MF, OBJ and PLY 3D files on Android from Files, Google Drive or Gmail, and you turn the model with your finger. It shows the size in millimeters, the volume and an estimate of the filament weight, and checks the model for holes before you print.

Use it to look at a model you downloaded before you send it to the printer, to check a part's size away from your PC, or to show a print to a friend. It suits 3D printing hobbyists, makers, students and anyone who gets STL files by email.

FREE AND PRO
Free to download. Opening, viewing, size and weight, and the print check are free to use as often as you like. The free version keeps your 10 most recent files and shows a small banner ad.
Pro is a one-time purchase, not a subscription: section cuts on X, Y and Z, measuring between two points, comparing several files side by side, unlimited recent files, and no ads.
Remove ads is a separate one-time purchase if the ads are all you want gone.

FAQ
How do I open an STL file on Android?
Tap the file in your file manager, Google Drive or Gmail and choose Layeria, or open Layeria and tap Open a file.

Can I open 3MF files from my slicer?
Yes. 3MF files open, including files with several objects.

How much filament will my print use?
Open Info. Layeria estimates the weight and length from the model's volume with a 0.8 mm outer wall and the infill you choose, for 1.75 mm filament.

Why does my model look like it is lying down?
Some programs save Y as up and others Z. Tap the up axis button in View to switch.

Do my files leave my device?
The files you open stay on your device unless you share them yourself. No account or sign-in is used.

LIMITATIONS
• Layeria views and measures models. It does not edit, repair or slice them
• Colors and textures saved in a file are not shown. Models appear in one color you choose
• STEP, FBX, GLB and other formats do not open
• Weight and length are estimates. Your slicer gives the exact figure for your settings
• Very large files can be too big for phones with little memory
• Files are not synced between devices
