I find the default fit on the Walksnail goggles X very uncomfortable – they press on my nose.
Theses shims will tilt the goggles up a notch, making them very comfortable to wear, with no light leak. I installed them by applying sticky velcro to both sides so they're not going anywhere (see photo).
I recommend printing them from a heat-tolerant materials like ABS or PETG, though TPU will work too (they don't need to be flexible).
Due to the form-fitting shape, it will need to be printed with supports. A raft can help too.
My print settings are:
0.2mm layers
Enable Support: Yes
Type: Tree (auto)
Style: Organic
Raft layers: 2
