Resize by Size 100 %

Side Size in mm

It scales equally on all three sides, so it doesn't get distorted.

File units

OBJ files don't say which unit they use. If the size looks wrong, change it here.

Triangles to keep 30 %

Fewer triangles = a lighter file, but the finest details are lost. For scans, 20 to 40% is barely noticeable.

Image size Background Part color

Rotate the view to the angle you want: the image comes out exactly as you see it.

What to include

"Just the shape" is lighter and enough to recover the part. Supports and skirt are never included.

Part thickness (mm)

A DXF is a flat drawing: this is the height given to every closed shape.

Stand it up (it's lying down)

This happens with files from Blender or video games, which use a different up axis.

An image of your model, no software needed

To post a model in a shop, on social media or on a model site you need a clean image. Here you open your STL, rotate it to its best angle, pick the color and download a PNG, without installing anything.

With a transparent background you can place it on any design; with a white background it's ready for an online store.

Making it look better

Turn it a little to the side and from above: the shapes read better.
Use the color of the filament you'll print with.
For online stores, white background and 1500 × 1500 px.

Tips

For social media, 1500 × 1500 px (square).
A transparent background lets you put it over another design.
If the model lies down, check "Stand it up".
For several views, rotate and download again.
