Printing Settings
Use the settings below for reference. The parts were printed on the Type A Machine Series 1. We used Simplify3D to slice the parts using our custom profile. You can download our profile for Simplify3D below.

Customize Design
You can modify the original solids in the CAD files to make a custom project.
Materials
The parts can be printed in different types of filament. The most common filaments like PLA and ABS will do just fine but you can of course experiement with copperFill, bambooFill, Semiflex, PET and Nylon.
Tolerances
The parts were tested with common printing settings (listed in the table). With a parameter of 2 shells, theres only a few areas where tolerances really matters - the port cutouts and the mounting holes.
Test fit the parts by inserting the top enclosure part over the Raspberry Pi. Check to see if the cutouts fit over the USB and ethernet ports. If the cutout is too tight, you can loosen it with a filing tool.
The standoffs with counter bores should fit the machine screws listed in the BOM. These can be threaded by fastening in the appropriate sized screw.
Bed Leveling
Any parts with large surface require a well leveled build plate. If you're using a heated bed, you can minimize warping. Blue tapers tape, build tak, and sticky adhesives can help keep your part flat and adhere to the bed.
Clean up
If there's any string or artifacts left over from retraction and oozing, clean up the part by trimming them off using a pair of flush snips.
