Gridfinity Brother P-Touch / TZ label printer cartridge holder

Holds 4 Brother TZ style printer cartridges, used in a P-Touch printer, in a 2x2 Gridfinity space. They are held ‘vertically’ so that they take up minimal gridfinity squares on your baseplate. There are no magnet holes in the base as this saves filament and I find them unnecessary.

There's a bit of wiggle room so with a bit of perseverance you can force the cartridges in without unwrapping them which I assume will save them from drying out quicker.
