3D Printing Enclosures
I drew up an enclosure in Autodesk Fusion 360 and designed each component so that I could design friction fit mounting points. I 3D printed the enclosure on several 3D printers to test tolerances (Printrbot Play, Flashforge Creator Pro, and Micro M3D).
If you don’t have access to a 3D printer, you could use a service like 3D Hubs to make it for you. I used PLA material to 3D print the parts, and they didn’t require any support material.
The enclosure was 3D printed with Proto-Pasta Aromatic CoffeePLA filament.
Slice Settings
Depending on your 3D printer, you may need to adjust the slice settings. I sliced the parts using Simplify 3D. They do not require any support material and are oriented to print "as is".
- Nozzle: 0.4mm
- Extrusion Multiplier: 1.0
- Extrusion Width: 0.48mm
- Layer Height: 0.2mm
- Nozzle Temperature: 220c
3D Printing with Conductive Filament!?
Yes, you can 3D print the pads using conductivePLA, which is a special blend of PLA with conductive particles. Proto-Pasta Conductive PLA filament is relatively easy to print with, and it's electrically conductive :-)
3D Printed Capacitive Touch Pads
If you're 3D printing the touch pads, I suggest you use a 100% infill to increase the conductivity.
