I made this parametric support bracket for my 10” HomeRacker setup after noticing that some of my 3D-printed rack mounts were putting too much stress on the rack screws. I found Ben Piep's Homeracker Foot/Feet and used that as a guide. These brackets help spread out that load and give the whole thing a bit more stability.

The Fusion 360 file is fully parametric, so you can adjust both unit length and height to fit your setup — whether you just need a small stabilizer or a taller bracket for heavier gear.

There’s also a .3MF file included with five preset versions 1–5 units long, 10mm cap height, which is what I found worked with most of my mounts.

Printing tips:

• Print topside dow
• I used Elegoo PLA+, and am going to mess around with PETG next.
• If you’re printing a 1-unit bracket, definitely use a brim—it helps with adhesion and prevents lifting.
