This spring needs to be printed in dry Bambu PLA Basic or stronger material. Do not Print in Matte, silk, or other types of filament that aren't built for strength.

I've only tested it with Bambu basic PLA and Bambu PETG HF and it works great in both

Keep in mind that this is a plastic spring and shouldn't be used for heavy duty applications like a trampoline or something similar; however, for being plastic, it's very strong
