Hextraction - Make ANY Tile Secret (feat. Secret Flipper Tile!)

Well, any tile within reason, at least.

The bread and butter of buttered bread of this design is actually this Tinkercad link. Even though the native 3D viewer detests me (and the model itself is atrocious), this is a hole punch to create space for a secret lid on your existing Hextraction tile designs!

Simply open/copy the link, import a Hextraction base tile of your choice, and download the newly-punched tile--no fiddling required! The result will automagically be cut down to size vertically and have six holes toleranced to accept either the regular-length or short-pegged secret lids floating around the wide web world. Print one of these to cover and your custom secret tile is good to go!

Bonus Features (the STLs):

• A regular-pinned secret lid with absolutely no design whatsoever. Goodbye, hard-to-print Riddler allusion!
• A complete Secret Flipper design, admittedly still requiring that M3x10 or 12 bolt. I use 12s because length.
• A Secret Asterisk, because it's a wonderfully almost-deterministic fantastically-useless secret design and I love it.
• A Secret Black Hole because I realize I'm increasingly an obstinate sadist. Thanks Biro100. Original in “Remixed From”.
• The Secret Lid Punch, but like, as a positive. Don't... print this. Use this as a backup negative if you hate HTML5 for some reason.

Not Included:

• New friends for when you bring 34 gray secret tiles to your local Hextraction meet and they decide that they would rather grab hamburgers than spend the next ten-minute-turned-hour-long game staring at a board full of perfectly-polished blank secret lids hiding tiles never before secretified.

NOTE: While this will punch any design, make sure that the original still "makes sense" with a secret lid. If the original has locked orientation or blocks some entrances/exits, so too will the secret version. You can't really hide physics, despite my best efforts.
