== Introduction ==
 +
{{ADFImage|Rasp-PiGRRL-2-3D-01.jpg|640px}}
 +
 +
== Material Options ==
 +
The top case, bottom case and shoulder mount should be printed in hard plastic like PLA, ABS or other. We recommend using PLA to minimize warping. ABS and other filaments requires a heated bed.

== Parts ==
 +
Download the parts and print them out accordingly - referencing the table below for material suggestions. If you don't have access to a 3D printer, use a service like <a href="http://3dhubs.com">3DHubs.com</a> to send them to you.

After the parts are finished printing, you'll need to tap the standoffs with screw holes to create the threads for mounting the components. Use a #4-40 and #2-56 sized tap or use machine screws.

 +
{{asm-text}}Be careful tapping the standoffs from the top -To prevent puncturing the surface, '''DO NOT''' tap all the way through the standoff. Be careful not to tap too fast or forcefully to avoid damaging the standoffs.

 +
== Test Fit Openings ==
 +
Use a hobby knife to remove any excess bits from printing. Lay the components over the standoffs to see if mounting holes line up. See if the port cutouts are in the right place. If they don't, use a filing tool to open them up.
 +
 +
== Finishing Parts ==
 +
You can smooth the parts by applying epoxy resin like Smooth-On's XTC-3D. To finish the surface, wait for it to dry and sand it down. Apply a filler primer paint and a colored top coat of spray paint to make it extra smooth.
