The idea for this part came from a small 2-armed planter I saw online. I thought something larger and more complex might be more useful. This design is my first attempt.

Unlike a real cactus this one is symmetrical with 3 layers of 7 arms each. Her's a 45 sec. video of the cactus with some rings and things loaded on it: https://youtu.be/XHy83y8ddFM. There are probably other uses for the cactus, but I haven't thought of them yet.

This part printed in just under 24 hours using a print speed of 80 mm.sec and a layer height of 0.200 mm. It will test your printer's ability to minimize stringing as it moves from arm to arm. So don't be surprised if you have to make some adjustments.
