Edit: Changed printer model (they added the Ender 3 V2), and also - I don't have Paypal set up, and I don't accept tips. Just let me know if you make it and add a photo if you do!

This cover is designed to allow your plant to grow unobstructed, but deny light to algae. The base goes on first, and the slide goes on second.

I suggest using a large brim due to a high chance of warping at the sharp corners.

I used clear PETG to test because that is what I had on hand at the moment, but you should use any opaque filament that is not PLA as that filament is biodegradable and hydroponic systems will probably accelerate that process.

Designed in Sketchup, sliced using Cura 4.8, and printed with an Ender 3 V2.

Use a brim for the corners, they like to warp.
