Open Ferrule for Drop Ceiling Tiles

I designed this as a quick pass-through opening in a standard 14mm drop-ceiling acoustical tile. It will fit larger tiles if required. Print at low-res and press-fit together. As is, the fit is _very_ tight…I recommend printing the outer ring at 101% for an easier fit without loss of friction.

I do not recommend excessive scaling. If you'd like to remake this at a different size, the [Tinkercad source files](https://www.tinkercad.com/things/2Y6x3R6iV6g-50mm-ceiling-tile-ferrule-for-14mm-tile) are publicly available.
