These are silicone rubber molding 2 piece patterns for making a real elastoplastic replica of a popular intergalactic sex toy from Rick and Morty.
The mold files are unified but you can separate them if you do not have enough build volume, all parts are printable without any supports, suggestions: liquid silicone does saturate the part with itself on the first pour, you can minimize it by printing 3 outside contours but it still does that. make sure that you cover the mold seam with a paper tape or something to keep the silicone from draining.
put the mold parts together and secure them with as much pressure as possible, they come with fixing pins but they might not provide enough pressure, you might want to use some tape around and as the silicone cures.
Mix the silicone with red powder pigment, or liquid depending on which one you get your hands on. mix it as along as you can.
add the silicone activator and observe the vulcanization of the container to know if the parts are fully cured
add some more from the entrance cavity as it may drain down.
CAUTION: do not open the mold until the parts are completely cured.
Knock yourselves out!
