Original model made by aalcock @ Thingiverse: https://www.thingiverse.com/aalcock/designs

For 1st gen Google WiFi “pucks” only, the original creator (link above) made a great install instruction picture, but in short:

- install at the desired location with tape or screws
- seat the puck's cable exit side to the 2 smaller tabs

- click the other side of the puck under the lip of the big tab

Added two holes to the model for screw mounting, but can still be attached with a double sided tape, powerstrips, velcro strips etc.
3 walls and 25% 3D honeycomb infill for some rigidity, roughly 10 grams more with 100% infill. Supports for overhangs, check that these are on.
