This is a tool/ plant pot which is inspired by the ceramic insulation discs found on power pylons in the UK. It's printable completely without supports and it's very easily scaleable to your size requirements.

Due to the rings and the overhangs, it's not a quick print, but it's extremely tough, with solid walls and a wide base to limit tipping/ leaning. For this reason it's excellently suited for use as a pot for heavier objects stationary, tools, cutlery etc.

Enjoy!
