Cylindrical Planter Pot Mold for Casting

thingiverse

Making a Mold: Print four outer mold parts - two perimeters and five percent infill is sufficient. Assemble them together using adhesive tape. Insert the inner mold part, printed in vase mode. Casting: Mix cement with water at a ratio of four to one. Pour concrete into the mold. Allow it to set for approximately 24 hours. Removing the Mold: Outer parts should detach easily - simply cut the tape and they will come loose. To remove the inner part, pour near-boiling water inside, wait until the plastic becomes pliable, then use a pair of pliers to pull it out.
