I have printed a few of the fantastic self-watering planters. One of these has my venus flytrap in and it was getting very large, with the traps spilling over the side of the planter.
To try to keep the traps vertical, I have produced this collar which fits over the top of the pot to provide a flange for the traps to rest on.

I am very much an enthusiastic amateur when it comes to designing. My designs tend to have two things in common
1) They serve a purpose. I like to design functional objects which have a real-world use. 3D printing for art is fine, but it's its real-world application which will take the technology forward
2) Wherever possible I design to be easy to print and try to eschew supports or complex printing; modifying the design where necessary and possible to achieve this.
