Stack-able Screw Pot (SD Cards)

I started drawing up a lovely simple design to hold 12 MicroSD cards
Then quickly realised that 12 slots wouldn't cut it.
So reworked it so that I can just throw them in.

You can print as many 'mid' sections as you like and they will screw together with one base and one lid.

My job involves a lot of swapping SD cards.
And a lot of replacing SD cards...

The swapping SD cards go in the top, the removed ones, no longer for our kit, go in the bottom one... and then into small piles around my house with random gcode files on them!

The lid and base print without supports, but the mid section needs supports.

Pics are of a poor print example. Too fast and via octoprint.
