Includes STL files to 3D print the reusable mold for making the concrete planters in this video!

I printed the mold pieces in PETG (affiliate link), using 0.10mm layer heights and 15% gyroid infill.

The mold pieces can be attached with hot glue, and the inside edges should be sealed with silicone.

The mold should be attached to a smooth base, such as melamine, and the inner mold can be made from a plastic container and a bottle cap (for a drainage hole).
