80mm Spacer including Mesh

This component ingeniously integrates the essential first spacer sleeve with the filter. I utilise a sponge, precisely cut to fit and loosely placed atop the filter, effectively preventing debris. This design elegantly eliminates numerous parts, negating the need for adhesives or screws. Designed for a 15mm outer diameter hose, yet readily adaptable in Bambu Studio via object scaling.
This piece directly affixes to the pot lid, serving as the primary spacer, ensuring ample space for the initial element, including your plants.

Regarding the print:
I employed PETG, configuring two wall thicknesses, 15% gyroid infill, and no support. The result is flawlessly functional.
