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.
These parts have been tested and 3D printed on an Ultimaker 2+ and 3 using PLA filament. The parts were sliced using CURA 3.x with the following slice settings.
Support Material / Overhangs
The top cover requires support material. The overhang angles on the support material can be increased to 60 degrees which will use less material and reduce the printing time. Features on the sides of the top cover part are 60 degrees so they don't need any supports.
The spool holder carousel assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, SAT and more.
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.
