Eastern Pondmussel (Sagittunio nasutus) with Internal Anatomy

Introducing our latest product: the Eastern Pondmussel (Sagittunio nasutus) model. The 3D printable model provides a detailed view of the internal anatomy of this freshwater clam species. It’s perfect for students, educators, and enthusiasts who want to explore the fascinating life cycle of this mollusk.

We offer two versions of the Eastern Pondmussel model. One version features a removable shell half that reveals the internal anatomy, while the other has a closed shell for a more traditional display. Our Eastern Pondmussel model is an excellent educational tool for biology, ecology, and environmental science classes. It provides a visual approximation of a dissection experience, allowing students to learn about the Eastern Pondmussel’s internal anatomy without harming any living organisms. The observable internal anatomical structures include:

  • gills
  • foot
  • adductor muscles
  • mantle
  • labial palps
  • foot retractor muscles

Furthermore, the version with a removeable shell to reveal internal anatomy has pre-drilled holes in the adductor muscles on both shell halves. These holes are to allow for small rare-earth magnets to be glued in place. The magnets then hold the shell halves together when the model is completed.

The digital files for the Eastern Pondmussel model are in STL format and are scaled to life-size, measuring 10cm in length, which is the approximate maximum size these clams reach.

Both the closed, and the removeable-shell-with-internal-anatomy models are packaged in a .zip archive, making it easy to download and get started with your 3D printing project. With this model, you’ll have an excellent addition to your collection or classroom display, showcasing the beauty and complexity of the Eastern Pondmussel.

Our tested print settings: Resin

We successfully printed the “dissected” version, in 2 pieces on a resin-based 3D-printer.

We successfully printed this model in grey resin on an LCD 3D printer using these settings:

  • Layer height: 0.05mm
  • Hollowed: False

Feel free to use these settings as a guide or use your own preferred settings. They’re just the settings that we used when printing.

Due to the nature of resin printing, you will have to determine your own exposure settings because they are different for every brand of resin and printer.

Our tested print settings: FDM

We successfully printed the “closed” version in PLA on an FDM printer using these settings:

  • Nozzle size: 0.4mm
  • Layer height: 0.12
  • Wall thickness: 1.2mm
  • Infill: 5% lines
  • Support material: True

We oriented the model such that the umbo and hinge were facing downward. If your slicer supports it, we recommend using a concentric support interface pattern to avoid any unsightly grid patterns where the support material meets the model.
