This gridfinity syringe holder is able to vertically store a syringe that has an 18 mm diameter, and a 36 mm long nozzle. The nozzle of my syringe is curved a bit, and the base of the nozzle is 8 mm in diameter, so this holder takes that into account. But if your syringe has a straight nozzle, then that should fit as well, as the gap for the syringe is not curved but fully vertical.
The holder fits in a 1x1 gridfinity slot, and is 9u high, including the base of the holder. This whole print can be done without supports, as the magnet holes are a snug pressure fit for 6x2 magnets, and have a bridge. Print it in whatever filament you like.
Just FYI: I store my syringe like this because I use it for IPA cleaning electronics, so this way I can easily grab it, and also keep it clean.
