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.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
