This is a variation of @kerlemakerspace's raised garden. I wanted something with a simpler design and also something I could fit for the pieces of wood I was recycling. The model is provided so you can adjust it easily for the width and height you need.

The current design is for 7/16"-20 and 3" long screws. Can be modified easily.

If you modify the hole it's easier to make it slightly larger, as you don't need it to thread to the plastic since the other side accommodates the hex nuts.

When drilling the wood planks, same advice use a slightly larger diameter. This will save you time by just sliding them instead of threading.

This is still a work in progress and I'm testing different accessories to make the beds self watering, add some ornaments, tools, and rods for mesh to protect from birds.

If you have any other ideas do let me know.

I have printed these so far in different settings but with:

0.4 Nozzle and 0.28mm layer you get 7h20 and ~300g
0.6 Nozzle and 0.42mm layer you get 4h45 and ~300g

I'm still trying to figure out how to reduce the amount of material needed while still being strong enough.

I have printed these in PETG and PC, no issues so far.
