Raised Garden Bed

I have a bunch of extra OSB subflooring boards. These brackets are a perfect fit for ½" board.

Rip cut the boards to whatever width and length you desire. I chose 4ft x 1.5ft to make a small square bed. 

Use M5 x 30mm stainless bolts and acorn cap nuts to avoid rust. 

Print in PETG, ASA, or ABS. I chose ASA for its superior heat and UV resistance. PLA will become too brittle over time and is not recommended. 

The center braces are not required but are useful for preventing bulging. Tightly tie a rope from anchor to anchor to prevent the weight of soil, mulch, and water from pushing the sides of the bed out over time. 

**Update 7-28-2025: 

1. Updated the inner bracket to make tool access easier.
2. Added edge guards to prevent splinters and reduce warping
