retroCART Enclosure v2 (with slot remix)

Saw retroCART (https://www.thingiverse.com/thing:4772631) on Hack-a-day and realized this meets a bunch of my accessibility needs and lets my retro itch get scratched. USB sticks and cables are getting too hard to manipulate and see and near impossible to line up and get into the back of the PC - this cart system makes that all that a breeze. Print it in nice Atari 800 almond or a good retro beige or khaki or whatever horrid color your childhood 8bit system was and add some chunky black rubber feet to the bottom and you have a good old breakout box alot like the old 5.25 drives and other addons those systems used. Just awesome

Forgive any sloppy work as this is my first attempt ever at OpenScad and stuff

Made the original retroCART slot tolerances about 1mm bigger to make the carts easier to insert and remove and this one fits the larger usb3 extension cables I had laying around.

Made the enclosure using the openscad from the Ultimate Parametric Box https://www.thingiverse.com/thing:1355018 and spent the better part of an entire day trying to figure out how to make the square hole in the front in openscad. Its a dirty hack but.. it worked.

Ultimately, I wanted to make this in the full size of the old drives but it's such a waste of desk space. print time. and filament but nothings stopping you. I'd like to have beveled the edge of the opening but I'm terrible at cad. I'd also like to have made it top loading like the Atari 800xl I had but again.. terrible. i'd also like to make 2 more to stack on top - one with a smaller width opening for usb2 devices but so that usb2 fits in the usb3 slot but not the other way around -- and one with rounded sides for usb c, so as my disability progresses, it's easier to determine what I'm using and what to grab in the stack of carts. Maybe someone in the community can expand upon this who's good at computer. The old 80's nerd in me wants to make a base unit with a hub that allows you to daisy chain them up using old 40 or 80 pin motherboard hdd cables or even old scsi cables and an exposed dip switch to pick where in the chain but sending usb over the flat cables.. but ugh.. effort. and maybe just a little too extra. :)
