Skadis T-Clip Mount

Cutout geometry for accessories that mount to an IKEA Skadis pegboard via the printable T-Clip system from Printables #256896. 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.

Usage

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:

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
