S300 Wall Cradle - Shiny Snake ITX Case

I’ve designed a pair of wall cradles for the S300: the STL file to print, the adjustable design file, a preview image and a README with print and install notes.

• Layout: the PC stands upright with its long side along the wall, so it only sticks out about 180 mm from the brick. Each cradle has a curved brace underneath, rounded edges, and chamfered faces that print cleanly at 0.2 mm layers.

• Front and back lips: 32 mm at the front and 25 mm at the back stop the case sliding or getting knocked off.

• Air gap: there’s a 30 mm gap behind the case so the side panel facing the wall can still breathe. Put the GPU side facing the room.

• Fixings: each cradle takes two countersunk screws. The top one sits above the back lip, and you reach the lower one through a hole in the curved brace.

• Strength: I designed for a 10 kg PC with a big margin. The stress on the PETG is tiny, and a 30 kg lean on the front lip puts about 400 N of pull on the top screw, which masonry plugs in solid brick handle comfortably.

• Printing: print 2 flat on the bed, no supports. Each one is about 184 × 144 × 40 mm, so it fits the P1S easily. The README has the Bambu Studio PETG settings.

• Installing: use 10g × 50 mm screws in 6 mm masonry plugs, or 6.5 mm masonry screws. Drill into the face of the bricks, not the mortar, and put the cradles about 200 mm apart (centre to centre).

Bambu Studio (PETG)

• Lay it flat as exported (profile on the bed). This keeps the layer lines running with the load.

• 0.2 mm layers, 6 walls, 5 top/bottom layers, 25–35% gyroid infill

• Smooth PEI or textured plate with glue stick, 70–80 °C bed, part cooling around 30–40%

• No supports needed. Expect roughly 180–220 g each.
