Corner brace for IKEA Besta cabinet

The original version of this model was created by Ed Daniel at Printables.

This is a corner brace designed for BESTÅ cabinets from IKEA. It helps reinforce the corners to reduce wobbliness in the cabinet.

I successfully printed it using Basic PLA with a 0.4 mm nozzle. The only adjustments I made were to the print profile: I used 3 wall loops and 25% infill. Everything else was set to default in Bambu Studio. The resulting print feels solid and sturdy.

While three brackets can fit on the P1S bed, I included only two in the design since they are often needed in pairs.

For assembly, I used M3 x 20 mm countersunk screws. However, a thicker screw might provide a better grip, as IKEA panels are somewhat hollow.

Update April 2026: Added an A1 mini profile with the copies rearranged to fit that tiny bed. People kept asking for it, so here you go.
