Ceiling tile hold-down clip

Keeps a drop-ceiling tile from lifting or rattling in its grid. The clip snaps onto the T-bar and two curved arms reach out to press down on the tile edges on both sides. Change the tile thickness and the bulb size to match your own grid.

Notes
Lying on its side, the layers run along the arms so they flex without snapping.

Assembly

  1. Lift the tile next door, or reach up past the tile edge, so you can get to the top of the T-bar.
  2. Sit the clip over the bulb with the arms pointing across the bar and press the dome until it clicks.
  3. To take it off, pull the dome straight up firmly. The jaws spread and let go.

Good to know

  • In the 3D view the pads sink 0.6 mm into the tiles. That's on purpose: it's how far the arms spring up once the clip is on, and it gives the downward press that holds the tiles.
  • I guessed the grid sizes. If your bar's bulb isn't about 6.5 mm wide, or your tiles aren't about 16 mm thick, measure them and set the Bulb width and Tile thickness sliders on Adjust first.
  • PLA softens around 55 °C, so in a hot plenum or attic print it in PETG instead.
