Cuttings Colonnade

Have you ever taken plant cuttings, then left em lying in an ugly glass of water for weeks? Well no more! Instead, buy yourself a bunch of floral watering tubes and print out these columns to hold them.

The columns interlock into a nice colonnade. Use a bit of 1.75mm filament to lock em together. There's a hole in the bottom, so if you want, you could fill it with dirt and use it for a pot instead.

Expected dimensions for the floral watering tubes are in a picture attached. I bought mine here: 

Floral Water Tubes/Vials for Flower Arrangements by Royal Imports, Clear - 3.5" (3/4" Opening) - Standard - 50/Pack - w/Caps https://a.co/d/2VZb3oR 

I am also explicitly asking that you don't sell prints of this thing or otherwise profit from it (see noncommercial license).  I designed this on my own time and I'm happy to see others print this for their own use, or as gifts.
