Printed with 0.4mm nozzle and 0.2mm layer height. No supports or brim.

Be careful taking apart your existing Mini Octopus to remove the chip inside. I can't remember what I used to take apart my original (transplanted over a year ago), but I recommend carefully using a flat metal object to pry the 2 halves apart.

The chip can then easily be set into the new shell. Seal the 2 halves of the new shell together with your favorite super glue.
