A simple Gridfinity nozzle holder for the three glue gun nozzles for the Ryobi glue gun (https://www.homedepot.com/p/RYOBI-Glue-Gun-Accessory-Nozzles-3-Piece-A193302/320243225). Since the nozzles took up two cubes of space, I filled the extra space with holes for glue sticks.

I used the Gridfinity Refined bases by grizzie17: https://www.printables.com/model/413761-gridfinity-refined

Gcode is for the Prusa Mini using grizzie17's suggested lightning infill.
