I made a holder for my PSX/2, Gamecube and Nintendo 64 Memory Cards. The holes might be a little tight but in my opiniion it fits as it should.
I once saw another holder here at thingiverse but this one had too many slots for my needs. It even had a slot for the sega saturn extension but this one is always in my saturn so I saw no need in this construction.
This baby can take up to two N64 memory paks, four PSX (or PS2 - same size) and two Gamecube Memory Cards.
No support needed (duh). 5% infill is enough.
