SKÅDIS Leaning Tower Controller Stand - Holds 3 Gamepads, Touches the Board Only at Its Foot

A controller stand for the IKEA SKÅDIS pegboard that looks like it should fall: a slim column leans 22° away from the board, touching it only at its foot, and three steps that reach further and further out carry three game controllers (Xbox / PS5 size). Yes, it really holds, and the numbers are below.

Details

• One piece, 52 mm wide. The column rises from the foot and opens a gap of 37 mm to the board at the top of the back plate. The steps end 103, 133 and 163 mm from the board, 74 mm apart in height; the whole tower is 170 mm tall.

• Each controller lies face up on a 52 mm step with its grips hanging on both sides of it (the gap between the grips of a standard controller is about 70 mm). The steps rise 7° outwards, so the controller slides back by itself against a small heel and cannot creep off the front. To take it, slide it out along the step: there is 15 mm of free space above each controller, even with the others in place.

• Pisa-style decoration inlaid flush on both sides: slate bands on the column, a slate cornice line on each step, terracotta heels and cap, and a small "HANMA".

• Printed lying on its side, so every layer contains the whole profile: all the bending stays inside the layers (the strong direction) and there is not a single overhang. One plate for the A1 mini with the AMS lite (174 × 163 × 52 mm): tower + 3 clips (2 + 1 spare). Bambu Studio: 3 h 06 min, 117 g (marble 113.5 g, slate 1.9 g, terracotta 1.5 g). Colour changes only in the first and last 0.8 mm.

Mounting

Push a clip down into each pocket at the top of the back plate (x = 0 and 40 mm, two slots apart in one row). Hold the tower 8 mm higher than its final position, push the clips through the slots and let it drop. The foot sits 76 mm below that row of slots and simply presses on the board.

How it was checked

Geometry in OpenSCAD with collision volumes (each test has a control that must collide), and the physics in a script that reads the real geometry and the slicer grams:

• Pegboard fit (common SKÅDIS test): clips go in raised 7.8 mm and drop without touching (0.000 mm³); a mounted clip cannot be pulled out (90.5 mm³) or pushed in without lifting (64.1 mm³); the tower does not touch board or clips (0.000 mm³) and cannot come forward (231 mm³).

• Controllers (simplified 152 × 106 × 54 mm model with grips and sticks): each one rests on its step without touching the tower, the board, the clips or the other two (0.000 mm³); 1 mm lower it hits the step (1704 mm³) and 2 mm further back it hits the heel (155 mm³). Each slides out along its step with the others in place (0.000 mm³); an 18 mm thicker controller would not (417 mm³). A 72 mm wide step would hit the grips (147 mm³).

• Why it holds: the load wants to peel the top of the tower off the board, pivoting on the foot. The two clip hooks resist with a lever of 72.8 mm (hook to foot). With the tower (115 g) and all three controllers (280 g each, centres of mass 77, 107 and 137 mm from the board) each clip pulls 6.7 N. The weakest section of a clip (4.4 × 3 mm, PLA in-layer 45 MPa) breaks at about 47 N, so the safety margin is 7.0. All 8 combinations of controllers present or missing were checked: margin 7.0 to 102, and the foot always stays pressed against the board (0.9 to 13.3 N), so the tower never unhooks, even empty.

• Control: the same tower with a short back plate (foot just under the clips) would pull 45 N per clip, margin 1.0: it is the long foot, not the clips, that makes the trick work. With only one clip the margin is still 3.5. A fourth controller on the outer step still leaves margin 5.0; the outer step takes 0.8 kg extra at its tip before the margin drops to 3.

• Each controller's centre of mass sits 26 mm inside the front edge of its step: a push of about 5 N (500 g) at that point would be needed to tip it forward. Control: with steps 40 mm shorter it would fall off.

• The tower itself: 0.5 MPa at the foot of the column and 0.9 MPa in the back plate, margins above 40.

Español

Torre inclinada para 3 mandos en el SKÅDIS: una columna que se aparta 22° del tablero y solo lo toca en el pie, con tres peldaños que sobresalen cada vez más. Parece que se va a caer, pero aguanta: cada clip tira 6,7 N y rompería a unos 47 N (margen 7). Una pieza, se imprime tumbada sin soportes: 3 h 06 min, 117 g.

برج مائل يحمل ثلاث يدات تحكم على لوح SKÅDIS: عمود يبتعد عن اللوح بزاوية 22° ولا يلمسه إلا عند القاعدة، مع ثلاث درجات تبرز أكثر فأكثر. يبدو كأنه سيسقط، لكنه يتحمل: كل مشبك يشد بقوة 6.7 نيوتن ولا ينكسر قبل نحو 47 نيوتن (هامش أمان 7). قطعة واحدة تطبع على جانبها دون دعامات: 3 ساعات و6 دقائق، 117 غراما.
