Plugging not used internal routing holes

I have a carbon frame "matte black UD" I have ran Di2 through the frame, so there is 1 un-used hole, and another 2 that a tiny di2 cable is loose in a massive oval hole.

I want to cover the un-used hole, and reduce the size of the other 2 so the Di2 cable sits in tightly. Does any one have any ideas or suggestions?

Also yes I do know that the bottom of the frame has holes water can drain out of. Its more of a cosmetic thing for me to want to solve the internal routing hole drama.

Perhaps you could form some plugs and grommets with this stuff: https://sugru.com/

CF frames are usually chosen for being lightweight, so I'd use cork.

Did you buy the frame new? It sounds like the "massive oval hole" is missing a cable stop grommet. On my 2014 Specialized Venge all of the frame pass-throughs have them. The first thing I'd do is check with the frame manufacturer and see if they exist, and if you can purchase replacements. Otherwise, you might be able to find a suitable substitute here Rubber Wire Grommets, Cable Pass Through Bushings & Bumpers

Good luck.

A recent purchaser of Trek Modane bike was told Trek has separate covers for Di2 or mechanical cable routing available.
On my frame the covers were meant for cable routing and had built in housing stops and small holes for the cable. Since
Di2 connectors are about the size of housing I had the choice of drilling out a cover or fabbing one. Since the covers were
rounded rectangle about 7/8x5/8" in size and held in by a small screw I took a small piece of 1/8" thick aluminum and
using only a drill press and belt sander made the holes and shaped it to fit. First one took 45 minutes, second one about 25
minutes. I could paint or anodize but elected to just use as is. Just needed two. It would have been easier with plastic but
I didn't have any thick enough.
The Di2 set up needs one hole for the rear brake and one hole for the Di2 wire.
