This SD card holder will keep your cards safe from dust, water and impact. The cap screws on within 2 full rotations and sits very secure, cards have very minimal play when the cap is on. Cards are very easy to remove and put in.
Made a small adjustment to the thread on the tray, as some people seem to have had problems. The thread now no longer runs all the way to the end. This should make overall printing easier. p.s. the lid is still the same, no need to reprint.
should print fine on any print setting
