An apparatus (100) for depositing an extrudable substance (102) comprises a bracket (104) and a sleeve (110), comprising an inner tubular sleeve wall (114) and an outer tubular sleeve wall (112). The sleeve (110) is coupled to the bracket (104) and is rotatable relative to the bracket (104). The apparatus (100) also comprises a cartridge (124), comprising an inner tubular cartridge wall (126) and an outer tubular cartridge wall (128), wherein the cartridge (124) is configured to be positioned between the inner tubular sleeve wall (114) and the outer tubular sleeve wall (112). The apparatus (100) additionally comprises a valve (140), configured to be communicatively coupled with the cartridge (124), a nozzle (152), configured to be communicatively coupled with the valve (140), a linear actuator (138) to control flow of the extrudable substance (102) from the valve (140) to the nozzle (152), an annular plunger (148), positioned between the inner tubular cartridge wall (126) and the outer tubular cartridge wall (128), and a twist-lock pressure cap (150), configured to be hermetically coupled with the cartridge (124).
