I have an Ender3 Pro and had been looking for an SD adapter that would work with a left mounted screen. Never found one, so I remixed this!
Printed and confirmed it works.

v1.2 has a (Very small) MicroSD organization holder remixed to the top in the otherwise unused space, and an SD slot on the front.

This stuff doesn't stick to the bed well, so I do the frist layer @ 210 and 65, then drop the temps after layer 1.
