This is a parameterized split grommet. Adjusts to most sizes of holes and wires.

Designed to be printed in TPU. I used the Bambu TPU 95A HF on an X1C.

Prints without supports or brims.

You will need to provide some clearance between the wire and the grommet when entering the parameters for allowing the grommet to fold on itself during installation so the flange can get inside the hole.

I created this because I drilled a hole in my printer enclosure to run a wire through and used this to keep the wire from fraying on the sharp edges of the hole in the sheet metal.
