The original design by OVERTURE3D fit my space perfectly. I adapted the models to be used with ½" (18mm OD) EMT conduit, which I had on hand, instead of purchasing 1" dowel rod.
Printed on a Sovol SV06+ with 0.6mm nozzle at 0.55mm layer height, 3 walls, 10% gyroid infill. I'm using only one center support for a span of 5 feet, which has held about 24kg with no issues. Just make sure you're fastening to studs.
The author remixed this model.
The original design by OVERTURE3D seemed like it would fit my space perfectly. I happened to have a 10' section of ½" (18mm OD) EMT conduit on hand (around USD $5 at hardware stores), so I adapted the models instead of using 1" dowel rod specified in the original design.
