I use the Patchpanel for 10 keystones 10" rack from just actual kevin although he did not have the blank insert so I descided to make my own in Fusion and here it is for you to use.

Print settings:

PETG - ASA or PLA

3 walls

25% infill

Gyroid

As for support, the profile is setup with normal/auto support but you may not require supports. I think it makes a better print.
