I had a vanilla orchid that really wasn't thriving.  I figured it needed something for its epiphytic roots to grab onto, but it really wanted nothing to do with the supports I provided for it.  I made this solution, where a mesh tube screws into the bottom of a pot.  You fill the mesh tube and the pot with sphagnum moss, and train the vine around the tube so the vine can sink its roots into the moss.  Water from the top.  You can screw on new sections as the plant grows.

My vanilla orchid just about doubled in size over the few months after repotting in this pot - it's growing dramatically faster now.

If you print both parts in the provided orientations (with the “male” screw on the top of the tube, upside down compared to its final assembly orientation), they require no supports.

During slicing, I recommend you merge in one of Stefan's excellent recycling logos to identify the plastic you're using: [https://www.printables.com/model/134180-recycling-symbols](https://www.printables.com/model/134180-recycling-symbols)

The screw threads are m45x3.

Update 2025-04-23: I've had this orchid in this pot for a little over two years now.  It's grown large enough to require three of the 150mm pole segments, and overgrow the top.  I created a topper for it that has small holes, to slow the water down to a trickle, and with hanger holes.  I also created an alternative base that's much smaller, for hanging.
