N64 Controller Pak Holder

This is a remix of stuffperson's Game Cart Holder. It allows for holding N64 Controller Paks, Rumble Paks, or Transfer Paks.

Unlike stuffperson's holder, this lays flat and has a square base.

I've uploaded a couple pre-made STLs to hold either 4 or 8 paks. You can use Customizer to create larger/smaller versions.

Since the transfer paks are significantly larger than the others; they do take up 2 slots deep. Their insert is also a different shape, so they have a little more wiggle room t
