3D Printing

3D Parts

STL files for 3D printing are oriented to print "as-is" on FDM style machines. Original design source may be downloaded using the links below.

CAD Assembly

This animation shows how the parts snap are put together. The TFT Gizmo is bolted to the Circuit Playground Bluefruit with hardware screws. The PCBs are fitted on top of the turtle body while the turtle shell snap fits on top. A plastic convex lens can be used to magnify the display. 

Design Source Files

The project assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, SAT and more. Electronic components like Adafruit's board, displays, connectors and more can be downloaded from our Adafruit CAD parts GitHub Repo.

Slicing Parts

The parts were sliced using CURA using the slice settings below. The parts were 3D printed using PLA filament. 

  • PLA filament 220c extruder
  • 0.2 layer height
  • 10% gyroid infill
  • 60mm/s print speed
  • 60c heated bed

Install Magnets

Neodymium magnets can be press fitted into the bottoms of the flippers. If the magnets are too tight to fit into, a deburring tool can be used to loosen up the tolerance.

Magnet Dimensions: 1/4" dia. x 1/8" thick

The small slits can be used to pop out the magnets. Use the tip of a small flathead screwdriver to pry them out of the holes.
