I have an FDM printer (Ender 3 clone) that is mostly 2020 aluminum extrusion as the frame. A few years ago I found some 2020 on sale and built a set of shelves for my wife’s plants out of it. (Now - I know. It’s not the most economical use of materials, but it was the middle of winter, and I didn’t want to go work in the garage. Plus the 2020 was on sale.) It’ll support a slew of plants over a 4-foot span (~1.2m) without any sagging or other concerns. It can be wobbly side to side, but that’s a matter of bracing and connectors.
I know. I was just seeing if you would notice. awkward laughter
(But thanks, I was trying to wing the conversion and started off with 3.3ft =1m and then did the numbers meme while my fingers typed gibberish.)
