I got a bit side-tracked in 3D design this morning, trying to work out some trays to hold seedlings. I had the bright idea of seeing I could make them tall enough to stack like modules on top of each other. The trouble was that trying to reinforce the top mean support material was called for (a waste of filament) and, going back to flat sides (no support required) was going to use a lot of material and take hours to print.

I think I might just go back to smaller, lower trays. Stacking up also has potential issues like reducing light at the lower levels or knocking over the stack. It was interesting to spend some time exploring but sometimes a bright idea isn’t the same as a good idea!
