Concrete Planter. This is a shorter version of the original Yoshimura Crease Pattern Concrete Planter I designed a month ago. It's exactly 50% of its original size but the rest of dimensions remain intact. It's 10cm tall which makes it perfect for cactus, succulents or aloes
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.
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.
You can keep the mould together using clothes pegs, I suggest this option instead of the clamps.
The plunger end has broken due to the beating with the hammer. I recommend using a steel rod (ratchet wrench extender in my case) and not to hit it directly with a hammer. I'd recommend to increase perimetral layers to at least 4, with 5 top layers to make it stronger. Despite of being broken I think I'll be able to use it a couple of times more.
- With regular PLA these molds have lasted exactly 5 castings until they develop catastrophic cracks :D. I suggest that if you plan to last almost forever, you use PETG as printing material.
Whichever is available
For the sides I used 5 perimetral layers of wall thickness to make it strong and durable.
