STL files for 3D printing are oriented to print "as-is" on FDM style machines. Parts are designed to 3D print without any support material. Original design source may be downloaded using the links below.
The strap and band are printed in Ninjaflex TPU filament. Use the following setting for slicing software. TPU material profiles are recommenced.
- printing speed: 30mm/s
- nozzle temperature: 240c
- retraction: off
- infill: 10%
- perimeters: 2
Slicing Case and Cover
No supports are required. Slice with setting for PLA material. Use white or translucent filament for the cover to diffuser the NeoPixel LED.
The parts were sliced using CURA using the slice settings below.
- PLA filament 220c extruder
- 0.2 layer height
- 10% gyroid infill
- 60mm/s print speed
- 60c heated bed
The Feather is installed at an angle and secured down by tabs with nubs. The vibe motor is press fitted into holder and secured with sticky adhesive backing. The DVR2605L is press fitted into the standoffs. The slide switch is press fitted into the holder. The tabs on the band and strap are press fitted through the loops in the case. The cover is press fitted on top of the case.
