i hope you guys like this new addition to my designs on dual 18650 mods.This is going off the previous version i had put up but with major changes (due to the switch from the other version taking up most of the space i decided to go with the tactical switches found on the hanna mods)... Im a big fan of kayfun rda's and so i developed a mod specifically for the new kayfun mini.the size of the mode has become much smaller. i was able to shave off over 1 cm from depth and place the atty on the side of the device. My printer needs a bit of calibration so i haven't yet been able to print one for testing but that doesnt stop you so the files are good and have no errors and are ready for printing.. i have not placed the switch hole (which i recommend be placed on the side of the usb port top corner above the chip) and i also have not or the holes for the atty platform.Waiting for some 510 connectors and not knowing the dimensions of them i was unable to finish the file. i will update in future. temporarily placed the atomizer platform at 5mm in height and have not placed the required holes for assembly and wiring yet... once i receive the 510 connector i will edit the file. once the file is complete you can buy it from shapeways search divamax. ...no files as yet currently under development stay tune thanks couple of sleepless nights hihihi... i used sketchup,netfabb and mesh lab programs for devalopment.
