Dodecagonal Wave Planter

Concrete Planter. Sides and interior part must be rotated 180º around the Y axis in order to not need supports (widest side always at the bottom).

GCode created with Slicer PE. 0.3mm layer height
For the sides: at least 5 perimetral wall layers, in order to make it strong and last many casts.

For the interior part: 30% infill. Designed with a drainage hole that acts as a plunger to tap it with a rod and a hammer in order to demould it. Also the square on the bottom is to insert a ratchet wrench and rotate it to free it (but it really didn't work, it's better to hit the drainage plunger with a rod and a hammer).

Remember to cover the mould with a good layer of vaseline, otherwise you won't be able to take it apart.

Sides and interior part took almost 18h each to print EACH, this is a big print but also I think it's worth it.

I used 4 parts concrete - 1 part water, but rule of thumb is to add water and mix it until it has a consistency similar to raw cookie dough.
