These are the first two box mod i did with the new DNA75. Box battery: http://www.thingiverse.com/thing:1572914 Bottom Feeder: http://www.thingiverse.com/thing:1561386 On thingiverse, in each project, u can read some information about size and what u need to mount. I think that are easy to print (in vertical, at 150 micron of resolution) and to mount. I printed all in ABS, 150 micron of resolution. Here all the DNA "full family" (on the right DNA200 2x18650 and DNA200 3x18650).
