Parametric Split Grommet

thingiverse

I wanted a way to shield wires without being encumbered by a bulky connecting lug that was too big for the grommet, so I devised a solution. The grommet unfolds when the container opens. It has a split that allows you to separate it after printing and a small amount of super glue holds each half in place securely. To install each half correctly, I had to drill a hole between the lid and the bottom of the case while the lid was closed, ensuring proper spacing. The OpenSCAD file is designed to be adjustable, allowing you to create your own custom design, but you'll need to adjust the z offset to get the spacing just right.
