Remixed Somnium's back cover to be a flat plate to simplify printing and overhangs. Also uses the screw holes for the circuit board to secure the back cover to prevent any rattling issues. Need to use 4 - M3x12mm screws to secure the back cover through the circuit board to the front. The screws securing the circuit board were very tight so keep that in mind.
Added a USB version to hold this cable: https://www.amazon.com/gp/product/B07ZSZQNWP/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
Slide the USB port into the holder until it snaps in, make sure the inner tabs line up to the channel on the usb.
W/O USB
Printed at 0.15 with PETG, 0.2mm will also work fine.
W/ USB
Print with Support for the usb tabs, use the 3MF for the support enforcers. Adjust the support pattern spacing to 0.2mm.
