Just a magnetic lock I made for my drawer to keep it shut.

It's designed for 10x4mm magnets, but the hole is actually 11mm to allow a tighter closure. You can adjust the horizontal expansion if you need a better fit.

Printed in white PLA with 0.2mm layer height and 20% infill.

I recommend using some double-sided tape even if you're planning to screw it in — it helps prevent rotation, especially on smooth surfaces.
