Description
Rainbow Trout (Oncorhynchus mykiss)
The Rainbow Trout, a dazzling swimmer found in freshwater habitats across North America and beyond, is renowned for its iridescent scales and adaptability. Native to cold, oxygen-rich streams and lakes, these fish are prized for their striking appearance, sporting a pinkish stripe running along their sides and speckled patterns across their bodies. They’ve also earned a reputation as energetic fighters, making them a favorite among anglers.
More than just a symbol of pristine wilderness, Rainbow Trout are ecologically significant, playing a vital role in aquatic ecosystems. They are also a cornerstone of aquaculture and sport fishing industries worldwide, with populations established in various countries. Despite their resilience, habitat degradation and invasive species pose challenges to wild populations in their native range.
Bring the essence of this iconic species to life with our 3D-printable STL files. Whether you’re creating a lifelike educational model, adding to your collection, or crafting a beautifully painted display piece, this model captures the elegant details of the Rainbow Trout. Perfect for enthusiasts of aquatic life or fans of intricate, nature-inspired models to paint!
The 3D printable, digital files are in STL format. They’re scaled to life-size and ready for you to print and paint them.
This Rainbow Trout is about 40cm long, which is as big as the freshwater rainbow trout is known to get.
The files are packaged in a .zip archive. This package includes a “solid” version with all fins attached, and it also comes split into parts so that the fins can be printed separately, and we also provide an option to print the body in separate halves.

Our tested print settings: FDM
We successfully printed Rainbow Trout model version that consists of front and back parts and individual fins in PLA on an FDM printer using these settings:
- Nozzle size: 0.4mm
- Layer height: 0.12
- Wall thickness: 1.2mm (AKA 3 wall loops)
- Infill: 5% lines (100% concentric for fins)
- Support material: True
We oriented the body halves so the flat surface was directly on the build plate. We printed the fins in transparent PLA and oriented them vertically such that the ends of the fins (i.e. furthest parts from the body) were facing the build plate . We have found when using Cura as our slicer, that we needed to add oversized manual support cubes to the downward facing surfaces of the fins to prevent them from toppling during printing.
