Render a minimal example (rounded plate with one cutout) so the README opens with a visual of what the library produces. Adds example.scad with the openscad render command in its header so the screenshot can be regenerated.

# Skadis T-Clip Mount
|
||
|
||
|
||
|
||
Cutout geometry for accessories that mount to an IKEA Skadis pegboard via the printable [T-Clip system from Printables #256896](https://www.printables.com/model/256896-skadis-t-clip-system). Print the clips separately from that model; this library produces the matching slot + recess on your accessory — a pill-shaped through-slot with a filleted cylindrical recess on the front face that seats the clip's cap. The preview above is generated from [`example.scad`](example.scad).
|
||
|
||
## Usage
|
||
|
||
```scad
|
||
use <../lib/skadis-t-clip/skadis-t-clip.scad>
|
||
|
||
plate_thickness = 5.4;
|
||
|
||
difference() {
|
||
// Your back plate, however you want to shape it.
|
||
cube([32, plate_thickness, 90]);
|
||
|
||
// One T-Clip cutout, centered at (x=16, z=45) on this plate.
|
||
translate([16, 0, 45])
|
||
skadis_t_clip_cutout(plate_thickness = plate_thickness);
|
||
}
|
||
```
|
||
|
||
For multiple mounts at the standard Skadis vertical pitch:
|
||
|
||
```scad
|
||
for (i = [0 : mount_count - 1])
|
||
translate([0, 0, bottom_z + i * SKADIS_PITCH])
|
||
skadis_t_clip_cutout(plate_thickness = plate_thickness);
|
||
```
|
||
|
||
## Modules
|
||
|
||
### `skadis_t_clip_cutout(plate_thickness, slot_w, slot_h, recess_d, recess_depth, recess_fillet_r)`
|
||
|
||
Negative geometry for one T-Clip mount: a pill-shaped through-slot plus a cylindrical recess on the front face whose two outer joints are filleted. The wall-to-floor joint (interior, concave from inside the recess) narrows the floor by `recess_fillet_r`; the wall-to-front-face joint (exterior, the plate's convex rim corner) is rounded so the rim opens to `recess_d + 2·recess_fillet_r` with a smoothly curved corner. Center the call at the desired `(x, z)` of the slot center and subtract from your plate.
|
||
|
||
| Parameter | Default | Description |
|
||
|-----------|---------|-------------|
|
||
| `plate_thickness` | (required) | Y depth of the back plate the cutout passes through |
|
||
| `slot_w` | 5.0 mm | Pill-slot width (Skadis nominal) |
|
||
| `slot_h` | 15.0 mm | Pill-slot length (Skadis nominal) |
|
||
| `recess_d` | 22.2 mm | Cylindrical wall diameter; floor narrows to `recess_d − 2·recess_fillet_r`, rim opens to `recess_d + 2·recess_fillet_r` |
|
||
| `recess_depth` | 2.9 mm | Total recess depth from the front face to the floor |
|
||
| `recess_fillet_r` | 0.8 mm | Fillet radius for both the rim and the wall-to-floor joint |
|
||
|
||
## Constants
|
||
|
||
| Name | Value | Description |
|
||
|------|-------|-------------|
|
||
| `SKADIS_PITCH` | 40 mm | Standard Skadis vertical/horizontal slot pitch |
|
||
|
||
## Coordinate system
|
||
|
||
| Axis | Direction |
|
||
|------|-----------|
|
||
| X | Horizontal — slot's short axis |
|
||
| Y | Pegboard outward — back face at Y=0, front face at Y=`plate_thickness` |
|
||
| Z | Vertical — slot's long axis |
