So been quiet for abit here but thats only because ive not been out taking photos but instead learning how to use a 3d printer and finding cool models to print and this is one of those cool models. a spiral sd card holder that i found online to replace the cheap kmart tackle holder i have been using for the longest time and that causing me to only shoot half a sd card because its a pain to manage but with this i can easily unscrew the cap and grab a sd card out and put the full one in a diffrent way (contacts down is full, contacts up is empty)
