Key rail 3-8 hooks, screw mount – 5 sizes, no supports

À propos de ce modèle

## What it is A key rail: one strip, several hooks, one pair of screws. Not one hook per key and six holes in the wall. Where it earns its place: hallway, workshop, garage, office, holiday flat. ## Dimensions (measured on the CAD solid) | number of hooks | Size (mm) | Volume (cm³) | |---|---|---| | 3 | 112 × 24.8 × 25 | 28.2 | | 4 | 138 × 24.8 × 25 | 35.7 | | 5 | 164 × 24.8 × 25 | 43.3 | | 6 | 190 × 24.8 × 25 | 50.8 | | 8 | 242 × 24.8 × 25 | 66 | ## Why this one Three to eight hooks on a 26 mm pitch - wide enough that a bunch of keys does not fight its neighbour. The upturned nose is 9 mm, so a key ring cannot jump off when the door slams. **Mounting — screw mount.** The back plate takes two countersunk M4 screws, 90 degrees, 4.5 mm through. On masonry use a 6 mm plug; on wood a 4 x 30 screw goes straight in. The heads sit flush, so nothing digs into the wall behind. ## Printing PETG or ASA, 0.2 mm layer, 4 perimeters, 25 % infill. PLA works indoors but creeps under a steady load — do not use it for anything that hangs. **No supports.** Every overhang was measured against 45 degrees in the orientation the file is saved in: 0.0 % of the surface stands steeper, which is nothing. Drop the file on the bed as it comes and print. ## In the download - **5 sizes**, each as STL, 3MF and STEP - a dimensioned PDF drawing - `README.txt` with the fit rule and the print settings - the STEP files are real solids, so you can edit them in any CAD instead of pushing a mesh around ## Tell me what you need **Liability.** These are workshop and household accessories, not parts for safety-critical use, for lifting, or for carrying people. Load figures are nominal: what a printed part actually holds depends on material, wall count, infill, layer adhesion and the surface it is fixed to. **This range is generated from parametric code, not modelled by hand.** A different size, angle, length or mounting foot is a parameter and a rebuild for me, not a new design.

The same goes for criticism: if something does not fit, tell me and I will correct it for everyone — buyers get the new file automatically.
