Print Files

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

  • Adafruit_Auto_Bike_Light_Bottom.stl
  • Adafruit_Auto_Bike_Light_Top.stl

Slicing

Supports were used on the bottom part, but not on the top.

The parts were sliced using CURA using the slice settings below.

  • PLA filament 210c extruder
  • 0.1mm layer height
  • 30% infill infill
  • 60mm/s print speed

The supports for the bottom half were set to have an 80-degree support overhang angle to avoid them being used in the hole that connects the Circuit Playground, as it wasn't necessary. However, that may depend on the printer being used.

Design source files

The project assembly was designed in TinkerCAD. You can find them here: top part and bottom part.

3D Print Design Option 2

This second design option mounts to the bike seat post and incorporates an integrated slide switch. It uses a M5 screw to secure the mount in place.

Slicing

No Supports are required, we just added 5 top layers to ensure the slide switch roof prints with enough layers.

The parts were sliced using CURA using the slice settings below.

  • PLA filament 210c extruder
  • 0.2mm layer height
  • 20% infill infill
  • 60mm/s print speed
  • 5 Top Layers
