Skadis hook, customizable: any depth and hook diameter

A single-piece hook for the IKEA Skadis pegboard. A narrow tab goes through the 5 x 15 mm slot and a latch behind the board hangs below it, so the hook only comes out when you lift it. Set the hook depth (20 to 90 mm) and the cup diameter (6 to 40 mm) for what you hang: a cable reel, a roll of tape, pliers or a headset.

It prints lying on its side with no supports, so the layers run along the arm where the load is. The tab width and the gap for the board are measured on the model below. Skadis boards are not all exactly 5 mm thick, so print one hook before a batch.

Parameters

Every slider in the viewer above, with the range the model accepts. The model rebuilds valid at both ends of each range.

Parameter	Range	Default	What it changes
Hook depth (reach from board)	20 to 90 mm	35 mm	How far the hook reaches from the board face to the outside of the cup.
Hook diameter (inner cup)	6 to 40 mm	14 mm	Inside diameter of the cup at the end of the arm. On short hooks it is limited so the cup never runs into the plate.
Lip height above cup centre	0 to 20 mm	6 mm	How far the front lip of the cup rises above the cup centre. 0 leaves an open half cup.
Arm / plate thickness	3 to 8 mm	5 mm	Thickness of the arm and the front plate in the direction of the load: the main strength setting.
Arm width	4.6 to 16 mm	8 mm	Width of the arm and plate, which is the print height when the hook lies on its side. The tab through the slot stays 4.6 mm.
Plate height below slot	14 to 24 mm	20 mm	Height of the front plate below the slot. A taller plate spreads the load over more of the board.

Proof: measured on the model

What the design must satisfy and what our CAD engine measured on the model at the default values. Only measured values are shown here; nothing on this page has been printed by us yet.

Requirement	Wanted	Measured
Tab width in the 5 mm Skadis slot	4.6 mm (0.2 mm play per side)	4.6 mm
Gap between the front plate and the latch, for the 5 mm board	5.3 mm	5.3 mm
Height of the tab and latch, which must pass the 15 mm slot	14 mm or less	13.1 mm
Hook depth from the board face	35 mm (the slider)	35 mm

valid solid, one body, 43.3 x 24.6 x 8 mm, fits a 256 x 256 x 256 mm printer; overhangs: 0.0% of surface would need support.

Print notes

Orientation: On its side, as shown: the hook's profile lies flat on the bed, so the layers follow the arm.
Supports: None
Material: PETG for heavy tools, PLA for light ones
Layer height: 0.2 mm
Settings: 4 walls and 30% infill or more
Hardware: None
Time and filament: About 10 min and 3 g at the default size: a rough estimate from the model's volume and surface (PLA, 15% infill, about 1 mm of walls, 0.2 mm layers), not a slicer.

Print one hook and try it on your board first. Skadis boards vary by a few tenths of a millimetre, and the 0.2 mm play per side is the model's assumption.
To hang it, push the tab into the slot about 9 mm above its final spot, then lower it until the tab rests on the bottom edge of the slot. It comes out the same way: lift, then pull.
Strength was not tested. Keep heavy loads close to the board and raise the arm thickness for them.

How it was designed

Designed with buildcad's AI agent, checked by the buildcad team. This is the request it started from and an edited account of what it did (more on how text to CAD works).

The request
An IKEA Skadis pegboard hook: plugs into the board's slots, hook depth and hook diameter adjustable, strong enough for a few kilos.

1
It wrote the checks before the model
Before drawing anything, the agent listed what had to be true and how to measure each item on the model: the tab narrower than the 5 mm slot (4.6 mm, so 0.2 mm per side), the hook depth equal to its slider, a 5.3 mm gap for the 5 mm board, and the tab plus latch shorter than the 15 mm slot.
2
First build: one measurement did not work
The first model (front plate, tab through the slot, latch behind the board, J-shaped cup) built as one valid body with nothing overhanging. Three checks passed at once, but the board-gap measurement returned nothing: its test box missed the part.
3
It probed the part instead
The agent shot rays through the hook to find where the plate, the gap and the latch really were, then rewrote the board-gap check as a probe. It measured 5.3 mm, as planned.
4
A virtual board and every slider extreme
It modelled a slotted 5 mm board and moved the hook into it: pushed in 8.7 mm or more above its seat, the path is clear; at 8 mm the latch hits the board; seated, nothing overlaps. That is where the 9 mm in the print notes comes from. The slider sweep then rebuilt all 12 extremes as one valid body each.
5
What it left for a real test
Its reply says what it could not check: a real board and the load. Both are in the print notes above.

One run of the agent: 4 min 31 s, about $0.52 of model time at list price (claude-sonnet-5-5). The model code behind this page is the code it wrote, unchanged.
