IKEA PAX Sliding Door Stopper - Reinforced 128866

A small replacement to keep your PAX sliding door working.

The original catch on my IKEA PAX wardrobe broke at one of its arms. I designed this replacement with a reinforced body and printed it in Bambu Lab PAHT-CF. It has been fitted and function-tested on my own wardrobe.

The two arms flex slightly as the metal mating piece enters, then hold the door in position. The design keeps that movement while adding material around the body. The photos show the printed replacement next to the broken original.

🔎 Compatibility and dimensions

- Designed for the PAX sliding-door catch style commonly sold as replacement 128866 . Compare the original part, fixing and metal mating piece before printing: PAX hardware varies between generations. - Approximate overall model size: 19 × 41 × 18 mm . - Print at 100% scale . Reuse the original fixing hardware. - This is a retaining catch, not a soft-close damper or a floor-mounted door stop. 🖨️ Tested print profile

- Printer: Bambu Lab H2D, 0.4 mm hardened nozzle. - Material: Bambu Lab PAHT-CF. - Settings: 0.20 mm layers, 4 walls and 80% grid infill. - Plate 1: one catch. Plate 2: two catches. - Keep the supplied orientation and automatic supports from the build plate. Remove supports carefully before fitting. - Dry the filament and use equipment compatible with carbon-fibre-filled nylon. Other materials have not been tested for this fit and flexing action. 🔧 Installation

- Record the position and orientation of the old catch before removing it. - Clean away support material and inspect the fixing hole and both arms. - Fit the replacement using the original hardware. Tighten securely without crushing the printed body. - Move the door slowly by hand. Check that the mating piece enters centrally, the arms flex and release, and the door remains correctly retained. - Recheck the fixing and arms after initial use. Stop using the part if it cracks, loosens or no longer retains the door. ✅ Tested on my wardrobe

The published files preserve the geometry and print settings used for the photographed repair. “Reinforced” describes the design change; no quantified strength increase or long-term fatigue life is claimed. Making a catch stiffer does not automatically make its flexible arms more durable.
