USB Stick Holder for Creality Ender 3 etc. (for included SD card reader)

thingiverse

This is a simple holder for the USB flash card reader that is included with most Creality 3D-Printers. It attaches to any Printer in the Ender 3 family as long as it uses the standardized aluminum extrusions. The holder utilizes the already existing lid of the USB stick as a retention mechanism to keep it in place which allows you to use it without having to remove and put back the lid each time while still keeping the reader safe while not in use.
