3D Printing

Three of four parts are photographed. Use the table below to reference parts

Printing Settings

Use the settings below for reference. The parts were test printed on the Ultimaker 2, Type A Machines Series 1 and the FlashForge Creator Pro. We used Simplify3D to slice the parts using our custom profiles. You can download our profiles for Simplify3D below.

230c Extruder

2mm Retraction

10% infill

2 Shells

60mm/s print speed

90mm/s travel speed

about 6 hours to print all parts.

Customize Original Design

The parts where designed in Autodesk Fusion 360. The design has been made public, and available to download in different formats if you'd like to use a different CAD software package.

Materials

We recommend using PLA material to reduce wraping while printing. Althought the parts can be printed in different types of filament, such as copperFill, bambooFill, ABS, 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.
