We recommend printing all the parts as they are oriented in the STL files. We used PLA for the hard components, and MatterHackers TPU filament for the soft buttons.
Print the Hard Buttons, Rings, and Cam plate first. We printed with 0.25mm layers, and 20% infill on all PLA parts.
In order to install the magnet rings in the Main Body, you will need to pause the print at the proper time.
This is easy to do in MatterControl. We printed the Main Body with 0.25mm layers. With 0.25mm layers, we need to pause the print at after layer 70 in order to place the magnet rings in the main body.
