Description

A flat rail, 200 × 46 mm and 22 mm deep, screwed to a wall or the back of a door. Four recesses are cut into its face. In each sits a paddle hook, 28 mm wide, hinged on a single steel rod that runs the length of the rail. Folded up, the hooks lie 4 mm below the rail face and the rail looks like a plain bar. Swung out, each hook lands on a shelf at the bottom of its recess and sticks 34 mm from the wall, with a 7 mm lip to hold a strap or a loop.

Use it for bags, scarves, a dog lead, keys on a ring, or headphones. The shelf takes the downward load. The rod only has to hold the hook in place.

Why it sells

Wall hooks are a listed seller category: an eufymake guide names wall hooks and cable organizers as Amazon Handmade items and says useful everyday items suit 3D printing, with practical gadgets at $8–$40; it gives no unit sales. A PrintPal guide puts organization and everyday items among top Etsy 3D models. Foldable hooks specifically are popular as free files: the MakerWorld hinged hook showed a 4.9 rating from 51 ratings in a search listing on 2026-11-10, with a commenter reporting it holds about 1 kg while another found it too weak for headphones; the Printables OOKER hook is a print-in-place purse hook that is 12 × 69 × 88 mm open and prints in about 20 min per the listing; and a parametric foldable wall hook uses a separate pin. The gap: those are single hooks with thin hinges that people report as weak. This is a rail of four with a printed shelf stop that carries the load, so the hinge only positions the hook.

Who buys it

Renters and small-flat households who want hooks that disappear when not in use, and gift buyers. Also people with front doors that open onto a narrow hall. They shop on Etsy, Amazon Handmade and craft fairs.

Design overview

• Rail body: 200 × 46 × 22 mm with four 29 × 40 mm bays, 20 mm deep.
• Four fold-up hooks, 28 wide × 38 long × 8 thick, each with a 5 × 7 mm lip at the tip.
• One 3 mm × 196 mm steel rod through all four hooks.
• Shelf stop: the 3 mm floor of each bay carries the arm's underside when deployed. This is the feature that fixes the weak-hinge complaint.
• Stowed hooks sit 4 mm below the rail face (arm front at z = 18, rail face at z = 22).
• Three countersunk screw holes, 4.2 mm, through the solid walls between bays.
• Design target: light loads, about 1 kg per hook (an estimate, not tested).

Dimensions

Parts list

Hardware and non-printed parts

• 3 mm × 196 mm steel rod ×1 (pivot rod)
• Cyanoacrylate glue, one drop at each end of the rod hole ×2
• No. 8 flat-head wood screw, 40 mm ×3, plus wall anchors on drywall

Fits and tolerances

• Hook arm in bay: sliding, 0.5 mm per side (28 mm arm in 29 mm bay). It is wider than the usual 0.2 mm because the arm must swing without rubbing the bay wall on a warped print.
• Rod in rail hole: 3.2 mm hole for a 3 mm rod, 0.1 mm per side. The rod is held at the ends with glue.
• Rod in arm bore: 3.4 mm bore, 0.2 mm per side, sliding. This is the pivot.

Modeling guide

Rail origin: back-bottom-left corner. +X along the rail, +Y up the wall, +Z out from the wall.

Rail body

1. Sketch on XY: rectangle 200 × 46. Extrude +Z 22.
2. On the front face (z = 22) sketch four rectangles 29 × 40 at X 12–41, 61–90, 110–139, 159–188, Y 3–43. Cut down 20 (floor at z = 2).
3. Pivot hole: Ø3.2 along X through the full 200 mm at Y 7, Z 14, with a teardrop top.
4. Three Ø4.2 holes through Z at (51, 25), (100, 25), (149, 25). Add a 90° countersink Ø8.5 on the front face of each.
5. Fillet the outer front edges 1.0, chamfer the back edge 0.4.

Hook arm Origin: pivot centre. +A along the hook length, +X along the rail, +B across the thickness.

1. Sketch the side profile on the A-B plane: stadium from A = −4 to A = 34, B = −4 to +4, pivot end radius 4. Extrude 28, centred on X = 0.
2. Lip: on the B = −4 face add a block A 29 to 34, B −4 to −11, full 28 wide. Fillet its outer corner 1.5.
3. Pivot bore: Ø3.4 through along X at the pivot centre.
4. Fillet tip corners 1.0 and long edges 0.6.

When deployed the hook rotates 90° about the pivot: its length points out from the wall, its underside (B = −4 side swaps with +4) rests on the shelf, and the lip points up. Check in CAD: the lip, which sits on the wall side when stowed, must stay at least 1 mm clear of the bay floor (lip lowest point z = 3, floor z = 2).

Print settings

Assembly

1. Drop the four arms into the bays, stowed, bores lined up with the pivot hole.
2. Push the 196 mm rod through the rail and all four bores.
3. Put one drop of glue in each end of the rod hole.
4. Screw the rail to the wall with the three screws.
5. Swing a hook out until its underside lands on the shelf stop.

Variants and upsells

• Two-hook (100 mm) and three-hook (150 mm) rails.
• Colour sets: charcoal rail with orange hooks, white rail with oak-coloured hooks.
• A 300 mm doorway kit with six hooks (this is outside the 220 mm bed, so split the rail in two and join on the rod).
• Next pieces: a matching key tray, a shelf with fold-up hooks.

Selling and distribution

Etsy and Amazon Handmade for the print, MakerWorld and Printables for the file. Price on material (about 115 g PETG), machine time (about 8.5 h) and a margin. Sell the print and the file. Licence the file with a commercial-use option. Include the rated load as "about 1 kg per hook, design target" in the listing, not as a safety rating.

Risks and IP notes

• Hinge pin load: mitigated by the shelf stop, which carries the downward force.
• Warped bays can bind arms. Mitigation: 0.5 mm side clearance and a brim.
• Overloading. Mitigation: state a light-load limit and do not market it for climbing or safety use.
• Saturation of foldable hooks. Mitigation: the rail format, four hooks per rail.
• Existing patents on folding hooks are possible. Do a quick search before selling at volume; this design uses a plain rod hinge and a shelf stop.
