[vcf-midatlantic] What do you guys always need for your vintage computing projects?

[Charlie's Computers]

(I know VCF East 2024 *just* ended and I'm not asking about plans for next
year, don't worry!)

I'm thinking of being a vendor at next year's VCF East or the year after
that. I'm getting into 3d printing and I'm going to buy a few more printers.

If I 3D printed brackets and adapters and more and sold them, what do you
guys always seem to need for your projects? Hard drive sleds? SCSI2SD
adapters for old Macintosh computers? Floppy EMU cases?

My 3d modeling skills are 0/10 so these things need to exist on Thingiverse
or yeggi.com (3d print search engine)

But I'll download Fusion 360 and try and figure out something, so if you
guys have any ideas for useful things I could make, let me know!

Sincerely,
Charlie
