Before it reaches your workbench
A few useful things to know.
Is this a physical model?
No. This catalogue is for digital model files, not a printed kit. When a release is available, its listing will describe the files and documentation included in the download.
Which scale and printer should I use?
Check the model details and release notes for the available scales and tested print settings. Use a scale-specific version where supplied: small features and assembly clearances do not always work when a model is simply enlarged or reduced.
Does the picture show a finished print?
Model previews may be digital renders. Refer to the image description and release notes to distinguish a digital model from a physical print test. Development previews are not a promise that every part has been printed.
What should I keep after downloading?
Keep a backup of the original release package together with its version number, licence and assembly notes. Read the instructions before arranging the parts in your slicer.
