It's a remake of perryluca "gopro mask mount" (https://www.thingiverse.com/thing:3012711),
with shorter "legs" for scuba googles that are not so deep... (Cressi Ocean)...
You need a small zip tie to fix the support to the mask, right between mask acrilic and silicone...
No need to drill or modify mask in any way...
Pls, post you makes...
