This is just a simple clip that snaps in flat against the 1515 extrusion channels inside the Sovol Zero, and leaves room for light-gauge wiring behind it (LED wiring, etc).

These are 15mm x 15mm, and sit very low against the extrusion, making them pretty inconspicuous. If you need a different size, download the step and just extrude it to the length you need in your CAD software of choice.

They're generally reusable; use a very thin flathead screwdriver or a bed/part scraper to pop them out. If you run a hot chamber, print this with a filament that's appropriate for the temperatures it'll be seeing.
