Planter

I uploaded both variants either to mold or just print the planter. You can as well download the matching pot as well.

If you want to mold it use leveling compound for the perfect result.

To get great results I recommend printing the mold with PLA because of its thermal properties. 2 perimeters/walls should be perfect. For a clean finish print with 0.1 layer height, use leveling compound and get all the bubbles out of the mold.

To release the molded part after curing (i recommend at least 2 days of curing) put it in the oven at 100°C so the plastic gets soft and slowly releases the concrete. To prevent crumbling use some layers of clear coat to protect the concrete.
