These models allow you to cover up a 2.5" diameter hole saw hole in drywall. They have an opening for routing cables through the hole..
There are two variants, for 5/8" and ½" thick drywall.
This was designed in Fusion 360, you can get the model here: https://a360.co/4hSnUZR. The model uses Fusion's Configurations feature, you can change the hole diameter and drywall thickness.
If you aren't able to make the changes yourself, let me know in the comments what hole diameter and drywall thickness you need and I can add a new version.
The author marked this model as their own original creation.
