<p>(Originally Uploaded to Thingiverse March 16, 2020)</p> <p>An upgraded version of the original GPH Zer0. Overall, it's design parameters was to be more durable overall, whilst allowing as much (if not more) airflow.</p> <p>List of changes:</p> <pre><code>*Top casing's vent grill has been thickened by .9mm *Bottom casing's vent grill has been thickened by 2mm *The ventilation grill structures has been changed to an interlocking hexagon pattern for increased structural integrity. *There is now a spacer plate to go between the Raspberry Pi Zero and the USB Addon Board. The nylon nuts are no longer required. *Material has been added below the USB plug to keep it from bending and cracking off the PCB. *Screw attachment holes reduced to 2mm. ( M2x12mm Screws will be used) *Infill has been increased from 20% to 25%. </code></pre> <p>Hardware:</p> <p>Raspberry Pi Zero W: <a href="https://www.adafruit.com/product/3400">https://www.adafruit.com/product/3400</a></p> <p>USB A Addon Board: <a href="https://www.amazon.com/MakerFocus-Raspberry-Required-Provide-Connector/dp/B077W69CD1?tag=tv-auto-20">https://www.amazon.com/MakerFocus-Raspberry-Required-Provide-Connector/dp/B077W69CD1?tag=tv-auto-20</a></p> <p>MicroSD Card: <a href="https://www.amazon.com/Sandisk-Ultra-Micro-UHS-I-Adapter/dp/B073K14CVB/ref=sr_1_3?crid=1QTX1Y34ANTZT&amp;keywords=16gb+micro+sd+card&amp;qid=1558389825&amp;s=gateway&amp;sprefix=16GB+mi%2Caps%2C158&amp;sr=8-3">https://www.amazon.com/Sandisk-Ultra-Micro-UHS-I-Adapter/dp/B073K14CVB/ref=sr_1_3?crid=1QTX1Y34ANTZT&amp;keywords=16gb+micro+sd+card&amp;qid=1558389825&amp;s=gateway&amp;sprefix=16GB+mi%2Caps%2C158&amp;sr=8-3</a></p> <p>M2x12mm Screws: <a href="https://www.amazon.com/gp/product/B0756VPKGL/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&amp;psc=1">https://www.amazon.com/gp/product/B0756VPKGL/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&amp;psc=1</a></p> <p>Software:</p> <p>Raspbian: <a href="https://www.raspberrypi.org/downloads/raspbian/">https://www.raspberrypi.org/downloads/raspbian/</a><br/> Pi-hole: <a href="https://github.com/pi-hole/pi-hole/#one-step-automated-install">https://github.com/pi-hole/pi-hole/#one-step-automated-install</a></p> <h3>Print instructions</h3><p>Standard Print Settings:</p> <p>Material: PLA<br/> Extruder: 212C<br/> Bed: 56C<br/> First Layer Print Height: .28mm<br/> Standard Layer Height: .2mm<br/> Wall Thickness: .40<br/> Wall Perimeters: 2<br/> Infill: 20%<br/> Infill Pattern: Gyroid<br/> Material Flow: 100%</p> <p>Support is needed for the bottom casing and spacer.
