Parametric Cable Grommet

Cable grommet in 3 pieces for a ¾" (nominal) desktop with 1 ¾" diameter hole:
* PETG core for flexibility in insertion and locking into table
* TPU gasket to avoid marring the table top
* TPU cap with slots for 3 power cables and 3 USB cables with movable slit to maintain seal

Fusion 360 file included so you can easily change parameters for your hole diameter and tabletop thickness.  My parameters are:
