Summary this is my dna133/75 3d printed mod . it will fit 2x 18650 batteries one dna200/75 board . id suggest to print in abs or petg. you may, or may not need supports for the board standoffs. id recommend printing 200 microns or less. typical time on print is 3 hours with lid and buttons, i designed the box with ease of install in mind. id ask, if anyone makes this, please post it. id like to see :) UPDATED TO V3!!!! added battery brackets and thickened up the battery tray to make it stronger. added a tiny bit of thickness overall aswell updated again!!!!!to v4 fixed placement of battery brace and made screen cut out bigger.
