Ender3 SD card slot locator

SD CARD SLOT LOCATOR
Do you fiddle about trying to get the SD card into that pesky slot?
You know the slot is somewhere under the print bed, but you can’t quite see it.
Print it out at .1mm for good definition.
The tab slides over the top of the regular USB slot to the left of the SD slot and presses home to fix tightly. There are no electronics or danger in pressing this home.
From now on the SD slot position is immediately obvious and easy to locate.
I also painted some white tippex (any white paint would do), onto the top edge of the my SD cards, which makes it easy to see from a distance, whether a card is resident.
This 11 minute print uses 527mm of filament and makes life a lot easier!
