Filament Options

We recommend using PLA material for this project. You can use ABS or other type of filaments but may require a heated bed. PLA prints with minimal warping and doesn't necessary require a heated bed.

Slice Settings

The table below is a general reference for slice settings. Every 3D printer is slightly different, so you might want to use settings you're familiar with.

File Name	Settings	Details
neohp-fcase.stl	190-210c PLA 90/150 mm/s .15 layer height No raft/support	Case for the Adafruit Feather 32u4 Bluefruit LE and 16x NeoPixel ring
neohp-bcase.stl	190-210c PLA 90/150 mm/s .15 layer height No raft/support	Case for the battery, 16x NeoPixel ring and slide switch
neohp-cover.stl	190c PLA 60/80 mms	Cover for the battery and Adafruit Feather 32u4 Bluefruit LE
neohp-cover-diffuser.stl	190c PLA 60/80 mms	The diffuser piece for the cover. Should be printed in white, transparent or glow-in-the-dark colored filament.

Dual Extrusion

We used a 3D printer (Flashforge Creator Pro) and Simplify3D (slicing software) to achieve a dual extruded printed cover. This allows two colored filaments to be printed in the same job. It's ideal for joining the cover with the diffuser. We used black filament for the outter part of the cover and glow-in-the-dark for the diffuser.

If the 3D printer you have access to doesn't have a dual extruder, you an alternative glue the pieces together. The tolerances might be too tight, so a filing tool or sandpaper can help.
