Summary

Tired of fighting with the card on back of machine ?

These make it a bit more user friendly - two styles.

Glue the card in the pocket. Will also fit into iMac slot.

12/31/2016 - Added holder for 'micro' sdcard - see below...

[Follow-up 1/4/17: Now using a MicroSDcard Extender along with the Adapter. Found one Extender that worked (shown in photo - bought at Amazon).
Also added a holder for the Extender.

I completely wore out the sdcard receiver on one of my Prusa printers (after only 6 months the contact-force diminished to very little).
I tried six different brands of 'sdcard Extenders' - only one worked and only on one of my Prusa printers (did not work on other Prusa or DaVinci).
I modified firmware per suggestions in other posts but that didn't fix it.
I decided to use a Micro-sdcard and leave the adapter in the printer.
Works great so I made a holder for the Micro.

You'll need to cut about 0.2 inches off the Adapter (so the micro sticks out enough for the holder).
