Not to worry! You can use a 3D printing service such as 3DHubs or MakeXYZ to have a local 3D printer operator 3D print and ship you parts to you. This is a great way to get your parts 3D printed by local makers. You could also try checking out your local Library or search for a Maker Space.
All of the parts are 3D printed with FDM type 3D printers using various colored filaments. All of the parts are separated into pieces to make 3D printing easier. Assembly is pretty easy and straight forward. Use the links below to download the STLs files.
3D Model & Components
All of the parts were designed in Autdoesk Fusion 360 and available to download and modify. The source contains 3d models of components such as the DotStar LED strip, 2200mAh battery, slide switch, and Adafruit Feather. You can use these models for reference in your future enclosure designs!
The stick is actually 248mm long, making it almost too big to fit on standard-size bed of a 3D printer. So, the model was rotated at 45 degrees, set diagonally across the bed. This orientation allows the stick to be 3d printed on a bed ~215mm x 215mm, like the Ultimaker 3.
Minimum bed-size: 185mm x 185mm
