This is a garden stake I modeled after some antique garden stakes that I have in my garden. If you're in a moderate climate, or using it for an indoor garden, PLA will be fine, but if using outdoors in a place with higher temperatures I'd recommend a stronger filament like PETG.
This prints face up and uses a filament swap, so you can do multicolor even without an AMS. I also have had lovely results from coloring the raised parts with a silver sharpie marker. I've used them for entire garden seasons without any of it wearing off or fading.
I've provided both an stl file as well as a pre-painted 3MF file for Bambu users. This file is for personal use unless subscribed to my commercial plan. Thank you!
