3D Printed PartsParts are designed to be 3D printed with FDM based machines. STL files are oriented to print "as is". Machines with dual extrusion or single extrusion setups are listed below with parts name and description. Parts require tight tolerances that might need adjusting slice setting. Reference the suggested settings below. |
Clips for Bike Frame
The headlight and box enclosure are designed to clamp onto the bike framing. There's a lot of different types of bikes, each with different sizes of framing. Take a moment to measure your bikes framing to ensure the clips will fit.
- Box clips: 38mm (1.5 inches) diameter
- Headlight clips: 23mm (0.9inches) diameter.
Dry Fit Parts
I suggest testing out the parts before installing the electronics. Print out the clips and try fitting them onto your bike frame. Fit the bhl-box-clip.stl parts onto the railing of the box enclosure – If the tolerances are too tight, use a filing tool to loosen up the edges. Fit the bhl-cover-jst.stl and bhl-cover-usb.stl parts onto the box enclosure.
Tap Mounting Holes
I used a set of screw taps to create threads in the various mounting holes. This greatly improves fastening screws. of the A mix of metric sizes are used here. M2.5 tap for the Feather mounting plate. M3 tap for the majority of the mounting holes.
Slice Settings
Use these settings as reference. Values listed were used in Ultimaker's CURA 3.X slicing software.
- 0.2mm Layer Height / 0.4mm nozzle
- 0.38mm Line Width (inner & outer widths)
- 60mm/s printing speed
- 20% infill

Dual Extruded HeadlightThe headlight was designed to be dual extruded using black and translucent PLA filament. When backlit, any geometry printed in translucent filament will illuminate and diffuse the lighting from the NeoPixels. If your 3D printer is not equipped with a dual extruder, you can 3D print the part in translucent PLA and mask certain areas with black acrylic paint. |

Dual Extruded Box EnclosureOne side of the box features "grill" details that are printed in a silver colored filament. This is purely for aesthetics and does serve any functionality (other than testing your dual extrusion setup!). You have the option to print a "single" extrusion version. |

Glitter Infused Filament from Fillamentum
The material used to print the some of the parts in this project are from Fillamentum. From the PLA Extrafill line of filaments, Vertigo Galaxy PLA and Rapunzel Silver PLA was used. Translucent PLA material was used to print the bhl-headlight-b.stl part.
