Nice job.

One thing you might consider with this kind of project is your choice
of tool. A fly cutter or hole saw turn less material into chips, so
therfore it tends to go faster and you have less of a job cleaning
up. Also, since less pressure is required your bending problem would
be less of an issue.

Yep, I will just bore holes with a smaller endmill, from now on. Did
that for yet another collet set (ER16), it was easy and pleasant and fast.
