10-inch Rack 0.5U Blank Filler Panel — 4/2 Hole, Standard & Reinforced Variants
A half-height (0.5U) blank filler panel for 10-inch (mini/half) racks — covers the gaps a full 1U panel can't, for a clean front and controlled airflow.
Mini racks are everywhere in homelabs now, but blank panels rarely come with the rack — and half-height ones almost never do. This is the 0.5U companion to the 1U set, covering the same mounting and fit options so one of the eight files drops straight into your rack.
Features
Slotted mounting holes for alignment tolerance
Stiffening frame (reinforced versions) is 217 mm wide — sits well inside the 222.25 mm rack opening, with margin for racks that don't follow the spec exactly
Quick to print, no supports needed
Variants
Pick one file along three axes:
Axis | Options |
|---|---|
Mounting holes | 4 — both slots per ear, screw it down properly; 2 — one slot per ear, fewer screws |
Reinforcement | Standard — 3 mm flat; Reinforced — 3 mm panel with a 3 mm stiffening frame on the inner side, minimizes warping |
Fit | Standard — 254.0 × 22.23 mm (exact 10"/0.5U); Loose — 253.5 × 21.73 mm for racks with tight openings |
Example: 10in_0_5U_blank_4holes_reinforced_loose.stl = both slots per ear, stiffening frame, loose fit.
Printing
Material: use your judgement — PLA is fine for a rack with no heat, PETG at minimum next to anything warm, and ABS/ASA if the neighboring gear runs hot
Layer height: 0.2 mm
Infill: anything — the panel isn't load-bearing
Supports: none — print flat on the front face (the filleted face on non-reinforced versions)
Hardware needed
Rack screws, quantity to taste — 2 is enough (1 can work, but expect it to sit slightly drunk); designed for standard M6 rack screws, but feel free to raid the screw drawer — just remember the slots are 6.5 mm
Fills the half-height gaps in your 10" rack — pick the holes and fit that match, print, done.
