Stop fiddling with SD card sockets in the back of your latest gadget, and streeeeeeeeeetch out with an SD Card Extender. This simple, but effective device gives you a long flexible cable, a pseudo-card on one end, and an SD card socket on the other. Plug in the SD card half and attach the socket wherever you like. This is a great hack for length constraints with 3D printers, single-board computers, data-logging kits and more. Get to your SD card in and out and safeguard against wear and tear.

The sockets are push-push. Insert the card to lock, and press in again to release it.  There's a wee pictogram on the socket, which shows the correct orientation. We used this with a Replicator 3D printer and also a Raspbery Pi Linux computer, and it was speedy and error free, but it is a hack, so be aware that high-speed and high-noise environments may end up not working.

Note some computers use the mechanical insertion of the card to detect when to mount/unmount - in which case this extender will confuse the host because the card can be electrically removed without being mechanically removed. Best used with systems where you can 'force' a mount/unmount or if the card is only replaced on reboot.
