A simple box mod (box battery) to use with the Evolv DNA25 or DNA40.
U need:

• a drip cup (in my sample i used a Svapiamo "easy flat 22 mm" drip cap;
• negative spring;
• positive contact;
• magnets 3x1 and 2x1;
• DNA40 from Evolv;
• some cable.
  I attach some variant of body with different drip cap holes and with or without bottom air hole and 3 longs of buttons.

A video about this box (italian):

To print:

• i suggest layer 0.15 for body and the two panel;
• i suggest layer 0.10 and low low (20 mm/sec) per the push buttons.

To mount i suggest to cable the circuit OUT of the box and after u insert in his space.

USE a soft/silicon cable.
