Support for cactus or small plants

My cactus was all bent over, but thanks to this support I was able to lift it up again so it can grow straight. Height of the pole: 180mm (20mm of drill). Diameter of the ring: 100mm. A drop of glue is enough to join the two parts. 
In the photo my support has some printing defects due to the poor adhesion of the piece to the printer plate, but overall it does its job.
